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.
<pre>Let middle piece's length be M
Then longest's and shortest's lengths are: 3M and 3M - 23, respectively
We then get: M + 3M + 3M - 23 = 40
7M = 63
Middle piece's length, or {{{highlight_green(matrix(1,6, M, "=", 63/7, "=", 9, inches))}}}
You should now be able to find the length of the other 2 pieces.
