A 36-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 3 times as long as as the first piece. If x represents the length of the first piece, find the lengths of all three pieces.

Explanation / Answer

x = country A x + 1 = country B x + 2 = country C x + x + 1 + x + 2 = 114 3x + 3 = 114 3x = 111 x = 37 country A = 37 country B = 37 + 1 = 38 country C = x + 2 = 39 x = smaller page x + 1 = larger page x + x + 1 = 33 2x + 1 = 33 2x = 32 x = 16 smaller 16 larger 17 x = first x +1 = second x + 2 = third x + x + 1 + x + 2 = 204 3x + 3 = 204 3x = 201 x = 67 The integers are 67, 68, and 69. 3(x + 4) = 2x - 3 3x + 12 = 2x - 3 x = -15 The number is -15 x = first 2x = second 3x = third x + 2x + 3x = 36 6x = 36 x = 6 The three pieces are 6, 12, and 18.
