Problem
A 60-inch board is to be cut into three pieces so that the second piece is 4 times as long as the first piece and the third piece is 5 times as long as the first piece. If x
represents the length of the first piece, find the lengths of all three pieces
What is the length of the first piece?
Solution
For this case x= lenght of the first piece and we can set up the following equation:
x + 4x + 5x = 60 inches
And then we can find the value of x on this way.
10 x = 60
x = 60/10 =6
The final answer for this case is x=6 inches
