If Jack's age is three years more than twice Tina's age,t,then which of the following represents the sum of their ages in terms of t??
(1)2t+3...(2)2t+3t..(3)2t^2+3t..(4)3t+3
Explain
4. We can substitute Tina's age as t. Jack is 3 years more than twice of Tina's age. That means that Jack's age is 2t+3. Hence, the sum of their ages is t+2t+3=3t+3.
