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.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
