Answer:
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 .
