The expression that represents Melanie's age is 1/2x - 3.
To find the expression representing Melanie's age, we need to break down the given information step by step.
Let's start with the given statement: "Melanie is 3 years younger than half of Emily's age, x."
To represent half of Emily's age, we write 1/2x.
Next, we're told that Melanie is 3 years younger than half of Emily's age. "3 years younger" means we subtract 3 from the expression 1/2x. So, the expression becomes 1/2x - 3.
Therefore, the correct expression representing Melanie's age is 1/2x - 3.
