Robbie, Jennie, Willie, and Kylie played a numbers game. Jennie picked a number but did not tell her friends. Robbie and Willie both picked a number as well, and Jennie described their numbers like this to Kylie.

Robbie picked a number that is nine more than four times Jennie's number.
Willie picked a number that is two less than three times Robbie's number.

Deciding to call her number, n, Jennie asked Kylie to write an expression that describes Willie's number.

Kylie came up with two expressions that equal Willie's number.

What are the equations?

Answers

Answer:

1. 3(4n+9)-2

2. 3*13n-2

Step-by-step explanation:(*)This symbol that looks like a little star means multiplication.


The two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34

What is Expression?

An expression is combination of variables, numbers and operators.

Robbie's number = 4J + 9, where J is Jennie's number.

Now we can use this expression to find Willie's number:

Willie's number = 3(4J + 9) - 2 = 12J + 25

So one equation that describes Willie's number is:

W = 12J + 25

Kylie found another expression that equals Willie's number, so we can find it by solving for J in Robbie's expression and substituting it into Willie's expression:

Robbie's number = 4J + 9

4J = Robbie's number - 9

J = (Robbie's number - 9)/4

Substitute this expression for J into Willie's expression:

W = 12J + 25

W = 12[(Robbie's number - 9)/4] + 25

W = 3(Robbie's number - 9) + 25

W = 3(4J + 9 - 9) + 25 (substituting 4J + 9 for Robbie's number)

W = 12J + 34

So another equation that describes Willie's number is:

W = 12J + 34

Therefore, the two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34

Quadrilateral KLMN is a rectangle. The coordinates of L are L(1,-4), and the coordinates of Mare M(3,-2). Find the slopes of sides KL, LM, MN, and NK.

Answers

L(1, -4)=(xL, yL)→xL=1, yL=-4
M(3, -2)=(xM, yM)→xM=3, yM=-2

Slope of side LM: m LM = (yM-yL) / (xM-xL)
m LM = ( -2 - (-4) ) / (3-1)
m LM = ( -2+4) / (2)
m LM = (2) / (2)
m LM = 1

The quadrilateral is the rectangle KLMN
The oposite sides are: LM with NK, and KL with NK
In a rectangle the opposite sides are parallel, and parallel lines have the same slope, then:
Slope of side LM = m LM = 1 = m NK = Slope of side NK
Slope of side NK = m NK = 1

Slope of side KL = m KL = m MN = Slope of side MN

The sides KL and LM (consecutive sides) are perpendicular (form an angle of 90°), then the product of their slopes is equal to -1:
(m KL) (m LM) = -1
Replacing m LM = 1
(m KL) (1) = -1
m KL = -1 = m MN

Answer:
Slope of side LM =1
Slope of side NK =1
Slope of side KL = -1
Slope of side MN = -1

The area if a dog kennel is 20 square feet. If the kennel is 4 feet.what is the width of the kennel?

Answers

Final answer:

The width of the dog kennel is 5 feet, obtained by dividing the area (20 square feet) by one of the dimensions provided (4 feet).

Explanation:

The student is asking for the width of a dog kennel, given that the area is 20 square feet, and one dimension (possibly the length) is given as 4 feet. To find the width, we can use the formula for the area of a rectangle, which is Area = Length × Width. Since the area is given as 20 square feet and the length is given as 4 feet, we can rearrange the formula to solve for the width:



Width = Area ÷ Length



Width = 20 square feet ÷ 4 feet = 5 feet



Therefore, the width of the dog kennel is 5 feet.

Final answer:

The width of a dog kennel with an area of 20 square feet and a length of 4 feet is found to be 5 feet using the area formula for rectangles, which is Area = Length × Width. The width of the kennel is 5 feet.

Explanation:

To determine the width of a dog kennel with an area of 20 square feet and a length of 4 feet, we can use the formula for the area of a rectangle, which is:

Area = Length × Width

We have the area (20 square feet) and the length (4 feet), so we can solve for the width:

20 square feet = 4 feet × Width

To find the width, we divide both sides of the equation by the length (4 feet):

Width = 20 square feet / 4 feet

Width = 5 feet

Therefore, the width of the kennel is 5 feet.

A cleaning company charges x dollars per hour to clean floors and y dollars per hour to clean the rest of a house.
-When the company spends 2 hours to clean floors and 3 hours to clean the rest of a house, the total charge is $84.
-When the company spends 1 hour to clean floors and 4 hours to clean the rest of a house, the total charge is $87.
Which ordered pair represents the hourly charges to clean floors and to clean the rest of the house?
A. (12, 20)
B. (15, 18)
C. (18, 15)
D. (20, 12)

Note: Please show work. My teacher checks it.

Answers

The answer is B. (15,18)

Solution:

First, let's set the variables first.

X = dollars per hour to clean the floor
Y = dollars per hour to clean the rest of the house

For the first statement, "2 hours to clean floors and 3 hours to clean the rest of a house, the total charge is $84"
We can put it into an equation.
         2X + 3Y = 84       ⇒    equation 1

For the first statement, "1 hour to clean floors and 4 hours to clean the rest of a house, the total charge is $87'
         X + 4Y = 87         ⇒    equation 2

Multiply first equation 2 by 2 to make the coefficient of both equations 1 and 2 the same.

Using elimination method in solving for x and y,

   (equation 1)              2X + 3Y = 84
   (equation 2)            2(X + 4Y) = 87   
                                    2X + 8Y = 174  ⇒ equation 3

Next, subtract equation 3 from equation 1.
            2X + 3Y = 84
      -   (2X + 8Y = 174)
        -------------------------
                  - 5Y = -90
                      Y = 18

Find X when Y = 18
@ equation 1  :    2X + 3Y = 84
                            2X + 3(18) = 84
                            2X + 54 = 84
                            2X = 84 - 54
                            2X = 30
                             X = 15
   
The answer is in ordered pairs of cleaning the floors and to clean the rest of the house. So, in the form (X,Y).

Answer: (15,18)

The hourly charges to clean floors and to clean the rest of the house are $15 and $18, respectively. We determine this by setting up a system of equations from the provided scenarios and solving for x and y.

To solve for the hourly charges to clean floors (x) and to clean the rest of the house (y), we need to set up two equations based on the information provided:

2x + 3y = 84 (from the first scenario)1x + 4y = 87 (from the second scenario)

Let's solve this system of equations step by step.

Step 1: From the second equation, we can express x in terms of y:
 x = 87 - 4y

Step 2: Substitute this expression for x in the first equation:
 2(87 - 4y) + 3y = 84

Which simplifies to:
 174 - 8y + 3y = 84

Combining like terms gives us:
 -5y = -90

Step 3: Solve for y:
 y = 18

Step 4: Now, plug the value of y back into the expression for x:
 x = 87 - 4(18)
 x = 15

Therefore, the hourly charges to clean floors and to clean the rest of the house are $15 and $18 respectively, which corresponds to option B. (15, 18).

Answer: 
The area of triangle QUV is 24 square feet

-----------------------------------------------

Explanation:

Segment TV is the base of the green parallelogram PRTV
The height is segment RS which is 8 ft. This is marked as the perpendicular dashed segment line (note the right angle marker). RS is perpendicular to SV, which in turn means RS is perpendicular to TV as well.

Area of Parallelogram = Base*Height
96 = TV*RS
96 = TV*8
96/8 = TV
12 = TV
TV = 12

Segment TV is composed of TU and UV, both of which are congruent segments. The single tickmarks show this. The instructions also state "the lengths of segment TU an segment UV are equal"
So TU = UV
TU + UV = TV
UV + UV = TV
2*UV = TV
2*UV = 12
UV = 12/2
UV = 6

The height of triangle QUV is also RS = 8 because triangle QUV is completely enclosed inside the parallelogram, and because RS is perpendicular to UV. The base of triangle QUV is the segment UV = 6

Area of triangle QUV = (base)*(height)/2
Area of triangle QUV = UV*RS/2
Area of triangle QUV = 6*8/2
Area of triangle QUV = 48/2
Area of triangle QUV = 24 square feet

what is the slope of the line through (6,9) and (7,1)

Answers

Slope of (6, 9) & (7, 1)

To find the slope, we use the equation : m = y₂-y₁ / x₂-x₁

**Remember : m = slope**

Let's say that (6, 9) is our first set of points, and (7, 1) is our second.

If those are our first and second points, then we now know this :

x₁ = 6, x₂ = 7, y₁ = 9, y₂ = 1

Now that we know that, we can simply plug those points into our slope equation.

m = y₂ - y₁ / x₂ - x₁

m = (1 - 9) / (7 - 6 )

Simplify.

m = -8 / 1

Simplify.

m = -8

So, our slope is -8.

Side AB is parallel to side DC so the alternate interior angles, angle ABD and angle BDC, are congruent. Side AB is equal to side DC and DB is the side common to triangles ABD and BCD. Therefore, the triangles ABD and CDB are congruent by _______________. By CPCTC, angles DBC and ADB are congruent and sides AD and BC are congruent. Angle DBC and angle ADB form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel. Which phrase best completes the student's proof?

Answers

Final answer:

The triangles ABD and CDB are congruent by the Side-Angle-Side (SAS) postulate, leading to the conclusion that quadrilateral ABCD is a parallelogram.

Explanation:

The triangles ABD and CDB can be proved congruent by the Side-Angle-Side (SAS) postulate. Since side AB is parallel to side DC, the alternate interior angles angle ABD and angle BDC are congruent. With both triangles sharing side DB and having equal sides AB and DC, the two triangles satisfy the conditions of the SAS postulate.

By the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) principle, angles DBC and ADB are congruent as well as sides AD and BC. Since angle DBC and angle ADB form a pair of alternate interior angles, this implies that AD is congruent and parallel to BC. This leads to the conclusion that quadrilateral ABCD is a parallelogram, characterized by its opposite sides being equal and parallel.

A pitcher needs more than one pitch to be effective. Dizzy uses his changeup only half as much as his fastball, and to save his arm, he throws a slider a third as much as his fastball. In a 110-pitch game, how many sliders would he throw?

Answers

Answer: Dizzy will throw 20 sliders in his 110 pitch game.

To write an equation, let x be the number of fastballs that he throws.

Therefore, the number of change-ups will be x/2 and the number of sliders will be x/3.

Now, add the equations together to get:
x/2 + x + x/3 = 110

Multiply the equation and solve to get:
3x + 6x + 2x = 660
11x = 660
x = 60

The number of fastballs is 60, dividing that by 3 gives us 20 sliders.
Final answer:

In Dizzy's 110-pitch game, he threw 20 sliders. The answer was found by setting up and solving algebraic equations based on the information given in the question.

Explanation:

This question is about using algebra to solve word problems. Let's denote the number of fastballs Dizzy throws as F, the number of changeups as C, and the number of sliders as S.

According to the question, Dizzy throws his changeup half as much as his fastball (C = 0.5F) and his slider a third as much as his fastball (S = F/3). We also know the total number of pitches (110) is the sum of F, C, and S pitches (110 = F + C + S).

We then substitute the expressions for C and S from our first two equations into our third equation to get: 110 = F + 0.5F + F/3. Solving this equation gives us F = 60. We substitute F = 60 into S = F/3 to find that Dizzy threw 20 sliders in the game.

Hello,

When we have a quadrilateral inscribed in a circle, the opposite angles add up to 180 degrees (supplementary).

Therefore, we can write and solve the following equation first with angles B and D.
3x + 9 + 2x - 4 = 180
5x + 5 = 180
5x =175
x = 35

Then, sub 35 in the expression for angle A and you will get:
2(35) + 3
70 + 3
73

Angle A is 73, that would make angle C equal to 107 degrees, because 180 - 73 = 107.

If Josie only has 60 cm^3 of wax, she doesn't have enough for either model candle.

The candle volume (V) is the product of base area (B) and height (h).

V = Bh
For the hex candle,
.. V = (21 cm^2)*(8 cm) = 168 cm^3

For the triangular candle,
.. V = (7 cm^2)*(14 cm) = 98 cm^3

Both candles are more than 60 cm^3.

The triangular candle is less than 160 cm^3. If that is the volume of wax Josie has, then she could make one of those.

What is x+2=-x+-2? Can you plz do it step by step!

Answers

To solve this equation, we are going to isolate the variable x.  To do this, we are going to begin by adding x to both sides because this will cancel out the negative x on the right side of the equation.

x + 2 + x = -x + x - 2
When we combine like terms, we get:
2x + 2 = -2
Next, we will try to continue to isolate the variable by subtracting 2 from each side to get the 2x term on the left by itself.
2x + 2 -2 = -2 -2 
When we combine like terms, we get:
2x = -4
Finally, to get x by itself we must divide by 2 to undo the multiplication of the coefficient of the term 2x.
2x/2 = -4/2
When we perform the division, we get:
x = -2
Therefore, x = -2.
We can check this answer by plugging it back into the original equation.  Our answer is verified because 0=0.
Your answer is that x = -2.

Step-by-step explanation:  We are given to find the value of c for which the following relation is a function :

R =  {(2,8) (12,3) (c,4) (-1,8) (0,3)}.

We know that

a relation is a function if each first element is associated with only one second element.

Since the first elements in R are 2, 12, -1 and 0, so, the value of c cannot be equal to these four values.

Therefore, the only option for c is 1.

Thus,  c = 1.

Option (b) is CORRECT.
