Answer:
24/25 walls per gallon
Step-by-step explanation:
to get per gallon, we want gallon to be zero.
5/8 gallon of paint: 3/5 of wall
multiply by 8/5 on both sides
1 gallon: 24/25 of wall
24/25 walls per gallon.
Answer: 
Step-by-step explanation:
The perimeter of a rectangle can be calcualated with this formula:

Where "l" is the lenght and "h" is the height.
The area of a rectangle can be found with this formula:

Where "l" is the lenght and "h" is the height.
In this case we know that:

Therfore, we can susbsitute them into
and solve for "h" in order to find its value:

Find two number whose sum is 3 and whose product is -40. These are -5 and 8. Then, factorizing, we get:

The positive value is the height. Then:

Since the length is 3 centimeters greater than its height, we get that this is: Then:

Substituting values into
, we get that the perimeter is:

H is less than or equal to 35
Just simplify each side and solve for the variable.
I think I know it. The number less than 3000 and if divided by 32 the remainder is 30 is 960.The number less than 3000 and if divided by 58 the remainder is 44 is 2552.
