Answer:
The correct answer is d. ( aka the last one.)
Step-by-step explanation:
1) You know that 43 inches is your starting point
and 53 is your end. that tell you your equation will look so.ething like this - _____ + 43 = 53
2) You know that she grew anaverage of 2.5 inches you just don't know how many years so you would write it as 2.5x. The x represents the unknown years. Giving you 2.5x + 43 = 53
3) Now you solve! Subtract 43 from both sides.
You should get 2.5x = 10.
4) Divide both side by 2.5 to get it away from x.
You should get 4! That means it was 4 years ago that Jessica was in 3rd grade.
