Question

McKenzie told her friend, “If you increase my age by 8, multiply that quantity by 1/2 , and then subtract 6, you get 5.” Write an equation that matches McKenzie’s description using x as the variable.

a) x+8x1/2-6=5

b)1/2x+8-6=5

c)1/2(x+8-6)=5

d)1/2(x+8)-6=5

Answer 1

D

Explanation:

This follows PEMDAS

This first thing to do is add 8, so this must be P aka parentheses.

A and B are eliminated

Next is to M aka mutiply by 1/2

This eliminates C because if -6 was in the parentheses this would mean it is the next step as () takes priority. And this is not the case

I hope Im correct!
