Question

Sam is 10 years younger than one-half the age of his aunt. Let a represent his aunt’s age. Which shows his aunt’s age written as an algebraic expression and Sam’s age if his aunt is 40?
StartFraction a Over 10 EndFraction minus 2; when a = 40 Sam is 2 years old
StartFraction a Over 10 EndFraction + 2; when a = 40 Sam is 6 years old
StartFraction a Over 2 EndFraction minus 10; when a = 40 Sam is 10 years old
StartFraction a Over 2 EndFraction + 10; when a = 40 Sam is 30 years old
