Question 1058819: The sum of the heights of three ladders is 143 feet. The second ladder is twice the height of the first ladder. The third ladder is three feet more than twice the height of the first ladder. Write an equation, and then solve it to find the height of each ladder.

You can put this solution on YOUR website! Let the first ladder be n. Then the 2nd ladder would be 2n, and the 3rd ladder would be 2n+3. So:
n+2n+2n+3=143
5n=140
n=28
The first ladder is 28 ft. long, the 2nd ladder is 56 ft., and the 3rd is 59 ft. long. ☺☺☺☺
