Note: Your teacher will grade your responses to questions 9–10 to ensure that your receive proper credit for your answers. A photo is 4 inches wide. It is placed inside a frame with a border that is x inches wide. The total width of the photo and the frame is 7 inches. Write an equation to model the situation, then solve the equation to find the width of the border.

Answer 1

Let's call the width of the border "x". Since the total width of the photo and the frame is 7 inches, we can set up the equation:

4 + 2x = 7

Now, let's solve the equation to find the width of the border:

2x = 7 - 4
2x = 3
x = 3/2

So, the width of the border is 1.5 inches.
