The left and right - hand margins on a sheet of paper are both 1.25 inches wide. The total width of the sheet t of paper is 8.5 inches. Write and solve an equation to find the width of the text area that lies betwen the margins.

and what is your thinking on this?

Let t = the width of the text area.

t = 8.5 - 2.5

Thank you.

To find the width of the text area between the margins, we need to subtract the widths of the margins from the total width of the sheet of paper.

Let's assign a variable to represent the width of the text area between the margins. We'll call it "x".

Based on the information given, the left margin has a width of 1.25 inches, the right margin also has a width of 1.25 inches, and the total width of the sheet of paper is 8.5 inches.

Using this information, we can express the equation as:

x + 1.25 + 1.25 = 8.5

To solve for x, we need to isolate the variable on one side of the equation.

Subtract 2.50 (1.25 + 1.25) from both sides of the equation:

x = 8.5 - 2.50

Calculating:

x = 6

Therefore, the width of the text area that lies between the margins is 6 inches.
