Answer: Choice A) Jada should have multiplied both sides by 108.
Reasoning:
x is a placeholder for some unknown value. We are dividing x by 108 to form the fraction x/108. To isolate x, we need to undo this operation. So we need to multiply both sides by 108. Doing so leads to the solution x = -48.
Answer:
Since the value is always multiplied by the same factor(19), the relationship is proportional.
Step-by-step explanation:
To see if the equation represents a proportional relationship, we see if the division of y by x is always the same
So
Equal, so proportional
