Acarpenter has a board that is 8 feet long. he cuts off two pieces. one piece is 3 1/2 feet long and the other is 2 1/3 feet long. how much of the board is left?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
