The number of rolls per wall is
.

Answer 1

The number of rolls per wall is one and a half rolls

Answer 2

x= 1.5 rolls

Explanation:

We use an algebraic expression to find the solution. Consider that the kitchen has 4 walls of similar characteristics.

Consider the variable x as the number of rolls that each wall requires.

x= number of rolls per wall.

If we say that 4 walls used 6 rolls: 4x =6 rolls

The question is, how many rolls does each wall use?

if we clear the variable x

`x=(6)/(4)`

So= x= 1.5 rolls
