9. Carson draws a scale drawing of a city park and a parking lot. The city 10 points park is in the shape of aright triangle with legs that are 3 inches and 4 inches. The parking lot is in a shape of a rectangle with dimensions of 1.5 inches and 2.5 inches. The scale for the drawing is 1 inch = 40 feet. What are the TWO actual areas for the shapes that are represented?
Answers
Answer:
The answer is below
Step-by-step explanation:
The scale for the drawing is 1 inch = 40 feet.
The right angled triangle has legs of 3 inches and 4 inches. Using the scale, the length of the legs is:
3 inches = 3 inch * 40 feet / inch = 120 feet and 40 inches = 4 inch * 40 feet / inch = 160 feet.
The area of a right angled triangle is half the product of the two legs. Hence:
Area of right angled triangle = 1/2 * 120 feet * 160 feet = 9600 ft²
The rectangle with dimensions of 1.5 inches and 2.5 inches. Using the scale, the length of the sides is:
1.5 inches = 1.5 inch * 40 feet / inch = 60 feet and 2.5 inches = 2.5 inch * 40 feet / inch = 90 feet.
The area of a rectangle is the product of the two sides. Hence:
Area of rectangle = 60 feet * 90 feet = 5400 ft²

Write a Linear Equation in
Point-Slope Form.
m = -5
(-3, – 7)
Answers
==================================
Work Shown:
m = -5 is the slope
(x1,y1) = (-3,-7) is the point the line goes through
Plug this into the point slope form below and simplify.
y - y1 = m(x - x1)
y - (-7) = -5(x - (-3))
y + 7 = -5(x + 3)
Side note: If we solved for y, we'd get y = -5x - 22 showing that -22 is the y intercept.

Hannah factored the expression 24xy + 15y. Her work is shown below.
1. GCF (24xy, 15y) = 3y
2. 24xy/3 = 8xy, 15y/3 = 5y
3. 3(24xy + 15y)
What are the errors in Hannah’s work? Check all that apply.
She divided by 3 instead of the GCF.
She found the wrong GCF.
She divided wrongly.
She didn’t complete step 4 and use the distributive property to be sure the expressions are equivalent.
She didn’t undistribute the GCF from the original expression.
Answers
Answer:
The correct answers for the multiple choice question are:
Option 1 (or A): She divided by 3 instead of the GCF.
Option 4 (or D): She didn’t complete step 4 and use the distributive property to be sure the expressions are equivalent.
Option 5 (or E): She didn’t undistribute the GCF from the original expression.
Step-by-step explanation:
I got it correct on Edge.
The errors in Hannah’s work are she divided by 3 instead of the GCF and she didn’t undistributed the GCF from the original expression.
The given expression is 24xy+15y.
Here, the factors of 24xy are
24xy = 2×2×2×3×x×y
15y = 3×5×y
So, common factors from both the terms is 3y.
Now, divide and multiply the given expression by 3y.
3y(24xy/3y + 15y/3y)
= 3y(8x+5)
Therefore, the errors in Hannah’s work are she divided by 3 instead of the GCF and she didn’t undistributed the GCF from the original expression.

Last month Albert earned half of what Betty earned, while Betty earned $5000 more than what Calvin earned. If Donna earned twice what Calvin earned and Albert and Betty together earned $900 more than what Calvin and Donna earned together, how much did each person earn?
Answers
Answer:
Calving earning = 4400
Betty earning = 9400
Albert earning = 4700
Donna = 8800
Step-by-step explanation:
Given that :
Calving earning = c
Betty earning = c + 5000
Albert earning = (c + 5000) /2
Donna = 2c
c + 5000 + (c + 5000) /2 = 900 + c + 2c
c + 5000 + 0.5c + 2500 = 900 + 3c
1.5c + 7500 = 900 + 3c
7500 - 900 = 3c - 1.5c
6600 = 1.5c
c = 6600 / 1.5
c = 4400
Calving earning = c = 4400
Betty earning = 4400 + 5000 = 9400
Albert earning = (4400 + 5000) /2 = 4700
Donna = 2(4400) = 8800

Answers
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
