Question

Use the order of operations to determine which expression matches the phrase "add 3 and 5, then multiply 7"? *

7 x 3 + 5

(7 x 3) + 5

7 x (3 + 5)

7 + (3 x 5)

Answer 1

Answer: 7 x (3+5)

Explanation: So basically it’s saying to “add 3 and 5” together, which is why they are in parentheses. THEN multiply 7 which implies that afterwards you multiply it by 7.

Answer 2

Answer:

7 x (3 + 5)

Step-by-step explanation:

The 3 and 5 are added together in the parenthesis, and then the 8 we get from that is multiplied by the 7. In order of operations questions, whatever is in the parenthesis is solved first.
