Mrs. Kang gave Caleb a collection of 25 marbles. Each month Caleb adds 4 marbles to his collection. Which inequality can be used to find m, the number of months after starting his collection when Caleb will have at least 70 marbles in his collection?

I did the math and got an answer of 17.5

Step-by-step explanation:

I divided 70 by 4 and got a result of 17.5. This probably means Caleb started his collection about 17 and 1/2 months ago. (I apologize if it's wrong)

17 and 1/2 months ago.

4 + 5 7/9= 9 7/9

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
