Answer:
Hi there! The answer would be B. 1/2x - 3.
Step-by-step explanation:
Since Melanie is 3 years younger, those three years would be subtracted off of Emily's age, x. That means neither A or C are correct because A is subtracting 1/2x from 3 and it's not C because it is adding 3 to 1/2x.
Hope this helps! :)
I also just took the K12 quiz.
