If r = 24 and t = 8, what is the value of the following expression? r + 72 ÷ t · 2

Hi there! For these types of problems, you will have to solve them by using order of operations, which is in the form of PEMDAS. First you do parenthesis, then exponents, then multiplication and division from left to right and addition and subtraction from left to right. So for this question, we divide first. t is 8. 72/8 is 9. Now, we multiply. 9 * 2 is 18. For the last steo, we add. r is 24. 24 + 18 is 42. There. The value of the expression is 42.
