Acontractor digs a hole for the basements of a new house that is 40 feet long and 10 1/2 feet deep. what is the width of the hole if 6,510 cubic feet of dirt are removed?
a.80 feet
b.81 1/4 feet
c.16 feet
d.15 1/2 feet

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
