4-46.

First, subtract 10 from 25 to find the amount left for the three equal parts.

25 feet − 10 feet = 15 feet

n = 5 feet

Next, determine how long each of the three pieces will be. If three pieces must add together to be 15 feet, how long are they?

$\frac{15}{3}=5\text{ feet}$

The process for solving this problem is the same as in part (a).
Remember to subtract 10 feet from the total before dividing it into three parts.

x = 100 feet

Follow the steps outlined in part (a).
