A pipe is 72 in. long. Cut three pieces of the following lengths from the pipe: 16 3/4 in., 24 7/8 in., and 12 5/16 in. Assume 1/16 in. waste in each cut. What length of pipe is left? Please answer step-by-step. Thank you!​

answer is because 4×10=40

and 98×4= is 392

40,392

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
