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?
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).
