Question

Which inequality best represents the problem? Tony is three years younger than his sister, Maureen. Tony's age is greater than 10. How old is Maureen? (Let m represent Maureen's age.)
1)m − 3 > 10
2)m − 3 < 10
3)m + 3 > 10
4)m + 3 < 10

Answer 1

Correct anser is 1.

Tony's age can be shown as T=m-3. Also know Tony is older than 10, so T>10. Substitute value of T into inequality.

m-3>10
