Question

A board, 56 cm long is cut into three pieces such that the second piece is twice as long as the first and the third is 6 cm longer than the second. Find the length of the shorter piece.

Answer 1

Answer:   10 cm

Step-by-step explanation:

Short Piece: x

Second Piece: 2x

Third Piece: 2x + 6

Short + Second +  Third = 56

  x     +     2x      + 2x + 6 = 56

                             5x + 6 = 56

                             5x       = 50

                               x        = 10
