Which expression represents the amount of material y that would be left over if x pieces of wood that are each 6 1 5 inches long are cut from a board that is 64 inches long?

y = 64  - 6.2 x   is the required  expression.

Step-by-step explanation:

Total length of the board =  64 inches long

Number of pieces cut from the wooden board  =  x

The length of each board  = 6 (1/5) inches  = 6. 2 in

The amount left over of the wooden board  =  y inches

Total length of board cut = Number of pieces cut ( Length of each length)

 = x ( 6.20 inches)  = 6. 2 x

The left over length  = Total available length - Total length cut

                                   = 64  - 6, 2 x

or, y =    = 64  - 6, 2 x

Hence,  y = 64  - 6, 2 x  is the expression  representing the amount of  material y that would be left over .
