Question 1194530
 A piece of pipe is 40 in. long. It is cut into three pieces. The longest piece is 3 times as long as the middle-sized piece, and the shortest piece is 23 in. shorter than the longest piece. Find the lengths of the three pieces of pipe.
--------------
L = longest piece, etc
---
L = 3M ---> M = L/3
S = L - 23
================
L + M + S = 40
L + L/3 + (L-23) = 40
2L + L/3 = 63
6L + L = 189
L = 27
----
M = 9
S = 4
