Question

A page of type in a certain textbook is 7 1/2
inches wide. If the page is divided into three equal columns, with 3/8 inch between columns, how wide is each column?

Answer 1

Your page has 3 columns + 2 (3/8) spaces to fit into a 7.5 inch space.
So, your equation would look like:
7.5 = 3x + 2(3/8)
Just need to solve for x and you're done.

Answer 2

3x = -7.5 + (3/8)

Answer 3

is it like this?

Answer 4

Not exactly, first isolate x so you'd have 3x = 7.5 - (6/8)

Answer 5

Then, simplify x = 2.5 - 0.25 = 2.25 so x = 2.25

Answer 6

so what do i do next
