Answer:
We kindly invite you to read carefully the explanation detailed below for further details.
Step-by-step explanation:
At first we understand that Diego converted length and wide units from feet to inches (
) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:
Step 1 - Unit conversion:
(
- Length)
(
- Width)
Step 2 - Applying scaling:
(
- Scaled length)
(
- Scaled width)
Because the perimeter is all the sides added:
P = side + side + side
4x + 3y = x + y + x + y + s
2x + y = s

Answer:
Names of the friends should be included.
Step-by-step explanation:
If you don't include the names of the friends people would get easily lost and confused.
So let's start out by labeling Ethan as X
Since 85 is 1/3 of what Ethan drove, that means Ethan drove 3 times of 85.
85= (3x) -21
85 -21 = 3x
60=3x
20 = x
The answer is 810 the digit would be 9 then you multiply by 90 it is 810
I hoped this helped!
