-2 (y + 3) – 6 (y – 10) = 42

1 Expand.

-2y-6-6y+60=42

2 Simplify  -2y-6-6y+60 to -8y+54.

-8y+54=2

3 Subtract 54 from both sides.

-8y=42−54

4 Simplify  42-54 to -12

-8y=-12

5 Divide both sides by -8.

y=-12/-8

6 Two negatives make a positive.

y=12/8

7 Simplify 12/8

y=3/2

or

y=1.5

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
