Solve for x. -3x = -15 x = -5 x = 5 x = -45
-3x = -15 divide both sides by (-3)
-3x:(-3)=-15:(-3)
x = 5
Answer:
The answer is b, 5
Step-by-step explanation:
-3x = -15
(it sometimes helps to flip it, so that's what I'm going to do here to help it to make more sense)
x(-3) = -15
x(-3) devided by (-3) = -15 devided by (-3)
when you devide a negitive by a negative the answer will be positive
the absolute value of 15 devided by three is 5
your answer is a positive five, or just 5

Find the rate of change for the situation. A Chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken 68 people
Answer:
The rate of change is of 0.25 lbs / person
Step-by-step explanation:
According to my research the formula for the Rate of Change is the following
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
In this situation we can use y for lbs and x for people. Since all the information was given to us in the question we can just plug the values into the formula above and solve for the rate of change.
[tex]\frac{17lbs-9lbs}{68-36} = \frac{8lbs}{32people} = 0.25lbs/person[/tex]
So we can see that the rate of change is of 0.25 lbs / person

a rectangular whiteboard in the ckassroom is twice as long as it is high. its perimeter is 24 ft. what are the dimensions of the whiteboard
Answer: The height of the whiteboard is 4 feet and the length of the white board is 8 feet long
Step-by-step explanation:
The height of the whiteboard is 4 feet and since the length on the white board is double the height it would be 8 feet long.
4+4=8
8+8=16
16+8=24
The dimensions of the whiteboard are 4 ft by 8 ft.
Explanation:To solve this problem, we can use algebra. Let's assume that the height of the whiteboard is x. Since the length is twice the height, the length is 2x. The perimeter of a rectangle is given by the formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
In this case, we are given that the perimeter is 24 ft, so we can write the equation as 24 = 2(2x) + 2x. Solving this equation, we get 24 = 6x. Dividing both sides by 6, we find that x = 4.
Therefore, the height of the whiteboard is 4 ft and the length is 2 * 4 = 8 ft.

Which ordered pair represents the solution to the system of linear equations?
(2,3)
(x,y)
x=2
y=3
This is because both lines meet at this direct point on the graph.
Answer:
Yes, the lines will intersect because the slopes are different. Also, both lines have a y-intercept of -7, so they both include the point (0, –7).
Step-by-step explanation:
The graph of a linear function is shown which word describes the slope of the line the choices and graph is below
negative
ExplanationLet's find the slope of our line using the slope formula:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
where
[tex]m[/tex] is the slope of the line
[tex](x_{1},y_{1})[/tex] are the coordinates of the first point on the line
[tex](x_{2},y_{2})[/tex] are the coordinates of the second point
From the graph we can get the points (-2, 1) and (2, -1), so [tex]x_{1}=-2[/tex], [tex]y_{1}=1[/tex], [tex]x_{2}=2[/tex], and [tex]y_{2}=-1[/tex]. Let's replace the values in our formula to find [tex]m[/tex]:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{-1-1}{2-(-2)}[/tex]
[tex]m=\frac{-2}{2+2}[/tex]
[tex]m=\frac{-2}{4}[/tex]
[tex]m=-\frac{2}{4}[/tex]
[tex]m=-\frac{1}{2}[/tex]
The slope of the graph of the linear function is [tex]-\frac{1}{2}[/tex]; since [tex]-\frac{1}{2}[/tex] is a negative number, the slope of the graph is negative.

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival. She only spent her money on ride tickets and admission into the festival. The price of admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation to calculate the cost for anyone who only pays for festival admission and rides
(c) Explain your answer to Part B.
Answer:
a) Here x represent number of ride tickets
z represent admission fees. = $20
y represent total cost.
Step-by-step explanation:
a) Here x represent number of ride tickets
z represent admission fees.
y represent total cost.
b) Given that,
$0.75 per ticket for the rides.
Number of tickets (x) = 18
Total spent (y) = $33.50
Total cost = (number of tickets)*(price per ticket) + admission fees
y =0.75x + a
We can calculate the cost for anyone who only pays for festival admission and rides.
c)
Put y = 33.50
x = 18
33.50 = 0.75*18 + a
33.50 = 13.5 + a
Solve for a,
Subtract 13.50 both the side
33.50 - 13.50 = 13.50-13.50 + a
20 = a
So, admission cost (a) = $20
An image of a book shown on a website is 1.5 inches wide and 3 inches tall on a computer monitor. The actual book is 9 inches wide.
Answer:
18 inches tall.
Step-by-step explanation:
The width of an image of a book shown on a website = 1.5 inches
and length of the book shown on the website = 3 inches
The actual width of the book = 9 inches
Scale of the book image = [tex]\frac{9}{1.5}[/tex]
1 inches = 6 inches
The actual length of the book = 3 × 6
= 18 inches.
The actual book is 9 inches wide and 18 inches tall.
The actual height of the book, given the image size can be found to be 18 inches.
How to find the actual height ?The image of the book is shown on the computer monitor at 1.5 inches wide, while the actual book is 9 inches wide.
To find the scale of the image on the computer monitor, divide the width of the image on the monitor by the actual width of the book:
= 1.5 inches / 9 inches
= 1/6
So, the scale of the image on the computer monitor is 1/6.
This means that every inch on the monitor represents 6 inches of the actual book.
Now, to find the actual height of the book, you can use the scale and the height of the image on the monitor:
= 3 inches * 6
= 18 inches

The angles in a triangle are such that one angle is 78 degrees more than the smallest angle, while the third angle is 4 times as large as the smallest angle. Find the measures of all three angles.
Let the angles are x, y and z.
Let the smallest angle is x
one angle is 78 degrees more than the smallest angle.⇒ y = x + 78 → (1)
the third angle is 4 times as large as the smallest angle. ⇒ z = 4 x → (2)
we should know that the sum of the angles of the triangle = 180°
∴ x + y + z = 180 →(3)
substitute from (1) and (2) at (3)
∴ x + ( x +78) + (4x) = 180
∴ 6x = 180 - 78 = 102
∴ x = 102 ÷ 6 = 17°
∴ y = 17 + 78 = 95°
∴ z = 4x = 68°
So, the measures of all three angles are 17°, 95° and 68°
what property does this demonstrate -1/4 = -0.25 then -0.25 = -1/4
A: Reflexive property
B: symmetric property
C: associative property
D: transitive property
Answer: B: symmetric property
Reflexive property states that for every real number x, x = x.
symmetric property states that for all real numbers x and y, if x = y then y = x.
associative property states that you can add or multiply regardless of how the numbers are grouped. =(like adding/multiplying like terms.
Transitive property states that for all real numbers x,y, and z, if x = y and y = z then x = z.
The equation -1/4 = -0.25 then -0.25 = -1/4 demonstrates the Symmetric Property of equality, which means order does not matter in an equation for it to be true.
Explanation:The equation you provided, -1/4 = -0.25 then -0.25 = -1/4, demonstrates the Symmetric Property of equality.
This property essentially says if a = b, then b = a. It shows that order does not matter in an equation; the elements can be flip-flopped, and the equality will still hold true. In your case, -1/4 = -0.25, and if you switch the order, -0.25 = -1/4, the equation still stays true. That's why we say it shows the symmetric property.

jack popped some popcorn, but 3 of the 150 did not pop. Determine whether or not each popcorn snack below has the same ratio of unpopped to total kernals as Jack's popcorn
Answer:
b and c
Step-by-step explanation:
Jack popped some popcorn, but 3 of the 150 did not pop.
the ratio of the jack's popcorn = [tex]\frac{3}{150}[/tex]
= [tex]\frac{1}{50}[/tex]
= 1 : 50
We will go through all the other given ratio to find whether they are same ratio of Jack's or not.
a. 2 unpopped out of 75 kernels = [tex]\frac{2}{75}[/tex]
= 2 : 75 This is not a match
b. 2 unpopped out of 200 kernels = [tex]\frac{4}{200}[/tex]
= [tex]\frac{1}{50}[/tex]
= 1 : 50 This is same
c. 1 unpopped out of 50 kernels = [tex]\frac{1}{50}[/tex]
= 1 : 50 This is also same
So b and c has the same ratio of unpopped to total kernels as Jack's popcorn.

Mary owned n sheep and Sam had exactly 4 times as many sheep as Mary. Mary buys 17 extra sheep and Sam sells 8 of his sheep. Sam still has more sheep than Mary. Form an inequality, in terms of n. Solve the inequality to find the least value of n. You must show all your working.
Answer:
The least value of n is, 9.
Step-by-step explanation:
Let n be the number of sheep in Integer.
Mary(M) owned the number of sheep is n i.e, M = n sheep
Sam(S) had exactly four times as many sheep as Mary , i.e, S = 4 n sheep
As per the given condition Mary buys 17 extra sheep
Now, Mary has total number of sheep, M = n +17 sheep
And Sam sells 8 of his sheep that means he has now,
[tex]S = 4n -8[/tex]
But, Sam still has more sheep than Mary i.e, [tex]4n-8 > n+17[/tex]
Solve an inequality: [tex]4n-8 > n+17[/tex]
Add 8 both sides we get;
[tex]4n-8+8>n+17+8[/tex]
Simplify:
[tex]4n>n+25[/tex]
Now, subtract n from both the side, we get;
[tex]4n -n>n+25-n[/tex]
Simplify:
[tex]3n>25[/tex] or [tex]n>\frac{25}{3}=8.33333333[/tex]
Since n is the number of sheep in integer,
then the least value of n is, 9.

solve the simultaneous equations
3x + 4y = 5
2x - 3y = 9
We label each equation
3x + 4y = 5 (1)
2x – 3y = 9 (2)
We now want to get rid of one of the variables (x or y). Lets get rid of x:
We need (1) and (2) to have the same number of x's so we multiple (1) by 2 and (2) by 3 so they both have 6 x's
6x + 8y = 10 (1)*2
6x - 9y = 27 (2)*3
Now to get rid of the x's we take one of the equations from the other. It is easier to do (2)*3 -(1)*2
6x - 9y = 27 (2)*3
6x + 8y = 10 (1)*2
-17y = 17
If we devide this equation by -17 we get
y = -1
We can plug this value of y into (1) to get
3x -4 = 5
add 4 to both sides of the equation
3x = 9
Divide by 3
x = 3
Now to check put x and y into (2)
6 - (-3) = 9
As this is true, we have the solution
x = 3, y = -1
