Answer:
1 wall is 0.75 gallons. 3 walls is 2.25 gallons.
Step-by-step explanation:
if 1 gallon covers 1 1/3 wall, divide 1/1.3333 = 0.75
multiply 0.75(1 wall) by 3.... 0.75×3=2.25
Hi.
First, I am going to give you some definitions.This will help you do the problems.
-Complementary angles have a combined sum of 90.
- Supplementary angles have a combined sum of 180.
10. 40+50=90- so YES.
12. 159+20= 179.-so NO.
Make sure you learn the definitions properly next time!

I have drop in a file for u to see it.
