Question

Cole’s age is 3 years less than his sister Tina’s age, t. If Cole is 18, which equation represents this situation, and how old is Tina?

A. The equation that represents this situation is t − 3 = 18. Tina is 21.

B. The equation that represents this situation is t + 3 = 18. Tina is 15.

C. The equation that represents this situation is 3 − t = 18. Tina is 21.

D. The equation that represents this situation is -3 − t = 18. Tina is 15.

Answer 1

Option A is correct answer.

Explanation:

Here age of Tina is given to be t

Cole's age = 3 year less than Tina's age ,that is t-3

which is given to be 18

therefore equating both we get

t-3=18

adding 3 both sides in order to solve for t ,we get

t = 18+3

t= 21 years

therefore Equation to find the age of Tina is t-3 =18 and

the age of Tina is 21 years.

Therefore option A is correct answer.

Answer 2

The Answer Is A

Explanation:

If cole is 18 and he is 3 years younger then tina then tina is 21 because if you add 18 and 3 you get 21 and to show the equation its t - 3 = 18.
