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?
a. y = 64 − 6 1/5x
b. y = 64 x − 6 1/5
c. x = 64 y − 6 1/5
d. x = 64 − 6 1/5y

i am not 100% positive but i believe it is A

Step-by-step explanation:

y=left overs

x amount of peices of wood that are 6 1/5... (this is a rate/slope) and the board is 64 inches which is our starting point. So... to find y I use the equation... y=mx+b...

y= 6 1/5x + 64

... but since we are subtracting(cutting) the 6 1/5 it might be negative... so... A

The answer is A.

Step-by-step explanation:

Solving for y, so 6 1/5 x pieces subtracted from 64

answer: i think it is (1,-2)
