I need help this work is getting graded and I’m confused

Answer 1

Question:

Solution:

Let us denote by x, the space between the desks, the distance between the first desk and the upper wall, and the distance between the bottom wall and the last desk. Then, according to the diagram and the statement of the problem, we get the following representation of the situation.

thus, we obtain the following equation:

`4x\text{ + 3(3)=24}`

this is equivalent to:

`4x\text{ +9 = 24}`

solving for 4x, we get:

`4x\text{ = 24-9=15}`

solving for x, we obtain:

`x\text{ = }(15)/(4)=3.75`

this represented in the latest graph is:

Therefore, the desks are equally spaced, with a distance between them equal to 3.75. So that, the correct answer is:

`3.75`
