student earns $11.75 per hour for gardening. If she worked 21 hours this month, then how much did she earn? 246.75 (blank 1) How much money would she make if she got a raise and earns $12.10 per hour and worked 21 hours? 254.1 (blank 2) How much more money per hour would she make if she got the raise? 7 (blank 3)

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

i think the answer is a.( -3, -1 )

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
