Exercise 52 Page 34

Recall the definition of a midpoint. Use it when writing an absolute value equation.

|x-b|=d

Practice makes perfect

We want fill in an absolute value equation of the following form.

|x- |=

First, let's take a look at the number line.

The given number line shows that b is at an equal distance d from both points a and c. Therefore, b is a midpoint. This means that a and c are solutions to the following equation. |x-Midpoint|=Distance to midpoint Now we can substitute values for the midpoint and distance.

|x- b|= d
