What is y+2=⅞(x-3) in standard form?
Answer:
7x - 8y = 37
Explanation:
y+2 = ⅞(x-3) (distribute ⅞ -- x times 7/8, -3 times 7/8)
y+2 = ⅞x - 21/8 (subtract ⅞x from both sides)
y+2-⅞x = -21/8 (subtract 2 from both sides)
y-⅞x = -37/8 <--- result of -21/8 - 2
Multiply both sides by 8 to get ride of fractions
8y - 7x = -37 (rearrange)
-7x + 8y = -37
It's better to have a positive coefficient for x if you can. So multiply both sides by -1. That just means changing the sign of every term on both sides, you get
7x - 8y = 37

Which of the following problems can be solved by finding 4 divided by 2/3?
A. 4 people equally share 2/3 of a pizza. How much of the pizza does each person eat?
B. How many 2/3 cup servings of soup are in 4 cups of soup?
C. A pie recipe requires 2/3 pounds of apples. How many apples are needed for 4 pies?
D A family ate 2/3 of a 4 foot sandwich. How much did he they eat?
Arthur chose A as the correct answer. How did he get that answer?
Step-by-step explanation:
Arthur got because a pizza is shared by 4 people. however only
2/3 of the pizza is there so it is divided by the four people.
The correct option is b.
The correct problem that can be solved by calculating 4 divided by 2/3 is determining the number of 2/3 cup servings of soup in 4 cups. By understanding how division of fractions work, we can see that there are 6 such servings in 4 cups.
Explanation:The subject matter of the question is related to basic division and fractions. Specifically, it's asking about when we would need to find the result of 4 divided by 2/3. Given the answer choices, option B is the correct one. The question here is not about sharing a pizza or calculating the quantity of apples for pies, or the amount of sandwich eaten. It's rather about how many 2/3 cup servings fit within 4 cups of soup. When we do the division 4 ÷ 2/3, we're essentially figuring out how many 2/3s there are in 4. This concept can be a bit tricky because dividing by a fraction is equivalent to multiplying by its reciprocal. The reciprocal of 2/3 is 3/2, so 4 × 3/2 = 6. Hence, there are 6 servings of 2/3 cup soup in 4 cups.

INEQUALITIES-PLEASE HELP! Tricia receives a $5 allowance every week. She also earns $6.50 for every hour that she baby-sits. Next week she wants to earn at least $21.25 to buy a present. Please write an inequality to math this equation.
Answer:
6.50x + 5 = 21.25 is the answer
Step-by-step explanation:
x=2.5
The inequality that represents Tricia's goal to earn at least $21.25 through her $5 allowance and $6.50 per hour from babysitting is E = 5 + 6.50h ≥ 21.25, where h represents the number of hours she babysits.
The student's question asks for an inequality to represent the situation where Tricia receives a $5 weekly allowance and earns $6.50 for each hour she babysits. The goal is to earn at least $21.25 to buy a present.
Let's denote the number of hours Tricia babysits as h. The inequality representing her total earnings E from both her allowance and babysitting will be:
E = 5 + 6.50h ≥ 21.25
This inequality implies that the sum of Tricia's weekly allowance ($5) and her babysitting earnings ($6.50 per hour multiplied by the number of hours h) should be at least $21.25.

Over the course of a year, a company goes from 115 employees to 124 employees.
Use the drop-down menus to build an equation that could be used to find the percent change, p, in the number of employees
Answer:
on the top is 124 - 115 whille in the bottom is 115
Step-by-step explanation:
To calculate the percent change in the number of employees, use the formula (Change in Quantity / Original Quantity) × 100. The original number of employees is 115, and it increased to 124, resulting in a change of 9. The percent change is approximately 7.83%.
Explanation:To find the percent change in the number of employees, you can use the following formula:
Percent Change (p) = (Change in Quantity / Original Quantity) × 100
In this case, the Original Quantity is the number of employees at the start of the year (115) and the Change in Quantity is the difference between the number at the end of the year (124) and the number at the start of the year (115).
So, we calculate Change in Quantity as 124 - 115 = 9.
Now, using the formula:
p = (9 / 115) × 100
Calculating this gives us the percentage change:
p = (9 / 115) × 100 ≈ 7.83%
The percent change in the number of employees is approximately 7.83%.

#SPJ5
Final answer:
To show that 2/3 divided by 3/4 equals 8/9, we multiply 2/3 by the reciprocal of 3/4, which is 4/3, yielding the answer 8/9. This illustrates that division by a fraction involves multiplying by its reciprocal.
Explanation:
To explain how the model shows that 2/3 ÷ 3/4 = 8/9, we need to understand division of fractions and the concept of reciprocals. Division of fractions is the same as multiplying by the reciprocal of the divisor. The reciprocal of 3/4 is 4/3. Therefore, to divide 2/3 by 3/4, we multiply 2/3 by 4/3:
(2/3) × (4/3) = 8/9
This demonstrates that dividing by a fraction is equivalent to multiplying by its reciprocal. We can also use familiar scenarios to rationalize the answer. For instance, we know that half of one half (1/2 × 1/2) equals one quarter (1/4) and this helps us understand the process - we are scaling a number by another when we multiply fractions.
When discussing multiplication and division of fractions, it is useful to remember that these operations are fundamentally linked; division is essentially multiplication by a reciprocal. Hence, dividing 2/3 by 3/4 is the same as multiplying 2/3 by the reciprocal of 3/4, which is 4/3, resulting in 8/9.

Factor −1/2 out of −1/2x+6.
The factored expression is
Final answer:
To factor −1/2 out of −1/2x+6, we identify the common factor, divide each term by −1/2, and write the expression as −1/2 times the simplified expression. The result is −1/2(x − 12).
Explanation:
To factor −1/2 out of −1/2x+6, we can think of pulling out the −1/2 as a common factor from both terms in the expression. Here's a step-by-step breakdown:
Identify the common factor in both terms. In this case, the common factor is −1/2.Divide each term by −1/2 (which is the same as multiplying by −2).Write the original expression as the product of the common factor and the simplified expression.Applying these steps, we get:
−1/2x divided by −1/2 equals x.6 divided by −1/2 equals −12.The factored expression is then −1/2(x − 12).So, −1/2x+6 factored with −1/2 taken out is −1/2(x − 12).

Shawn hikes up a mountain, back down the other side, then around the front of the mountain back to his truck. How far did he go if n = 5 and m = 6?
Answer:
The distance Shawn went is 40.
Step-by-step explanation:
Given:
N= 5 and M =6
Mountain hike = N = 5
Back down the other side = 2N+1 = 2×5 + 1 = 10 + 1 =11
From Mountain back to truck = 4M = 4×6 = 24
We need to find the total distance he went and can be calculate by adding Mountain hike with back down the other side and then from Mountain back to truck.
Total distance Shawn went = Mountain hike+ Back down the other side + From Mountain back to truck = 5 + 11 + 24 = 40
Hence Shawn went the distance of 40.

Given: △AKM, KD ⊥ AM , AK = 6, KM = 10, m∠AKM = 93º Find: KD
The length of KD in triangle △AKM, with AK = 6 and KM = 10, and m∠AKM = 93° is 10, since KD is the height of a right triangle and KM is the hypotenuse.
The question asks to find the length of KD in triangle △AKM where KD is perpendicular to AM. Given AK = 6, KM = 10, and m∠AKM = 93º, we can solve for KD using trigonometric ratios.
Since KD ⊥ AM, we have a right triangle △KDM.
We know the hypotenuse KM and angle AKM, so we can use the sine function, where sin(AKM) = opposite/hypotenuse, to find the length of KD. The sine of angle AKM (which is slightly adjusted from 93º to 90º since we are looking for the height in a right triangle) gives us:
sin(90º) = KD/ KM
We know sin(90º) = 1 and KM = 10, so:
1 = KD / 10
Therefore, KD = 10.

use the method of completing the square to solve y²+y-7=0
Answer:
y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2
Step-by-step explanation:
Solve for y:
y^2 + y - 7 = 0
Add 7 to both sides:
y^2 + y = 7
Add 1/4 to both sides:
y^2 + y + 1/4 = 29/4
Write the left hand side as a square:
(y + 1/2)^2 = 29/4
Take the square root of both sides:
y + 1/2 = sqrt(29)/2 or y + 1/2 = -sqrt(29)/2
Subtract 1/2 from both sides:
y = sqrt(29)/2 - 1/2 or y + 1/2 = -sqrt(29)/2
Subtract 1/2 from both sides:
Answer: y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2
Answer:
y=sqrt(29)/2-1/2, -sqrt(29)/2-1/2
Step-by-step explanation:
y^2+y-7=0
completing the square,
(b/2)^2=(1/2)^2=1/4
(y+1/2)^2=7+1/4
(y+1/2)^2=28/4+1/4
(y+1/2)^2=29/4
y+1/2=sqrt(29/4)
y=sqrt(29/4)-1/2
y=sqrt(29)/2-1/2
y=-sqrt(29)/2-1/2
The area of a rectangle is 28 square meters. The length is 7 meters.
What is the width of the rectangle?
meters
To find the width of the rectangle, use the formula Width = Area ÷ Length. Given an area of 28 square meters and a length of 7 meters, the width is 4 meters.
The area of a rectangle is calculated using the formula:
Area = Length × Width
Given that the area is 28 square meters and the length is 7 meters, we can find the width by rearranging the formula:
Width = Area ÷ Length
Substitute the given values into the formula:
Width = 28 square meters ÷ 7 meters = 4 meters
Therefore, the width of the rectangle is 4 meters.

A wooden beam is left parenthesis 6 y squared plus 5 y plus 1 right parenthesis6y2+5y+1 meters long. If a piece of length left parenthesis y squared minus 12 right parenthesisy2−12 meters is cut off, express the length of the remaining piece of beam as a polynomial in y.
Answer:
5y² + 5y - 11
Step-by-step explanation:
The length of a wooden beam is as a function of y
L(y) = 6y² + 5y + 1
and a piece of length y² - 12 is cut off the remaining piece is
6y² + 5y + 1 - y² - 12 = 5y² + 5y - 11
To find the remaining length of the wooden beam, subtract the length of the cut-off piece from the original polynomial. Simplify the expression to get the final answer: 5y² + 5y + 13 meters. This represents the remaining length of the beam.
Finding the Remaining Length of the Wooden Beam:
We start with the original length of the wooden beam given by the polynomial 6y² + 5y + 1 meters.
We need to subtract the length of the piece that was cut off, which is given by the polynomial y² - 12 meters.
First, write down the original length of the beam:
6y² + 5y + 1
Next, identify the length of the piece cut off:
y² - 12
Subtract the second polynomial from the first:
(6y² + 5y + 1) - (y² - 12)
Simplify the expression by combining like terms:
6y² - y² = 5y²
5y remains unchanged.
1 - (-12) = 1 + 12 = 13
So, the remaining length of the beam is:
5y² + 5y + 13
The remaining length of the wooden beam, expressed as a polynomial in y, is 5y² + 5y + 13 meters.
