Jonathan was 45 inches tall when he started kindergarten. He grew an average of 2.5 inches every year. Jonathan is now 62.5 inches tall. ​Which equation can be used to find how many years ago Jonathan started kindergarten, and how many years ago was it? A. (45 + 62.5) ÷ 2.5 = x 7 years

B. 2.5x + 45 = 62.5 7 years

C. (45 + 62.5) ÷ 2.5 = x 43 years

D. 2.5x + 45 = 62.5 43 years

B; 2.5x + 45 = 62.5

Step-by-step explanation:

Since the current height is 62.5, and the starting height is 45, then all you have to do is subtract 45 from 62.5, then divide that by 2.5 to get your answer, which should be 7 years.

Hopefully this helps- let me know if you have any questions!

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
