Help me pls this is a test I need a good grade

81.05/20 is the better deal and the unit rate is $4.05

Step-by-step explanation:

hopefully this helps :)

the second deal is better. the unit rate is 4.05/gal

Step-by-step explanation:

106/25=4.24

81/20=4.05

4932,9180,7625 are divisible by 9

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
