Based on the scatterplot, what is the approximate gas mileage for a vehicle
weighina 4000 pounds?

step-by-step explanation:

answer:

125 yards

explanation:

75+50=125. that is my answer

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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
