Answer:
I think the answer is 10 hours
the 11.95 seems wrong
Step-by-step explanation:

multiply by 22.5 y
3.75 y + 22.5 = 6y
y = 10
The answer is 380. You divide 1520 by 4 and that gives you the answer.
Answer:

Step-by-step explanation:
<u>Step 1: Define</u>
4y - y(3 - 7y) + 5 + 2(8 - y)
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute parenthesis: 4y - 3y + 7y² + 5 + 16 - 2y
- Combine like terms (y): 7y² - y + 5 + 16
- Combine like terms: 7y² - y + 21

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)
