NEED ASAP! A contractor poured concrete to form the set of steps shown below. Each step rises 8 inches and is 10 inches deep. The image shows a set of 3 steps with width, length and breadth as 8 in., 10 in., and 36 in. respectively. Question What volume of concrete did the contractor use? A. 8,640 cubic inches B. 17,280 cubic inches C. 18,432 cubic inches D. 25,920 cubic inches

c. 1,233 miles

step-by-step explanation:

there's the chart

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.
