Question

Shea wrote the expression 5( y + 2) + 4 to show the amount of money five friends paid for snacks at a baseball game. Which expression is equivalent to the one Shea wrote?

Answer 1

Answer: To determine which expression is equivalent to the one Shea wrote, we can first evaluate the expression 5(y + 2) + 4. The parentheses indicate that we should first perform the operation inside the parentheses, which is to add 2 to y. This results in 5(y + 2) = 5y + 10.

We can then add 4 to both sides of the equation to get 5y + 10 + 4 = 5y + 14. This expression is equivalent to the one Shea wrote, 5(y + 2) + 4.

Therefore, the expression that is equivalent to the one Shea wrote is 5y + 14.
