Question

Thomas has 12 more marbles than twice the number of marbles Andrew has. Andrew has x marbles. Which expression represents how many marbles Thomas has?

Answer 1

2x + 12

Explanation:

Let

x = number of marbles Andrew has

Number of marbles Thomas has = 2x + 12

The expression which represents number of marbles Thomas has = 2x + 12

If Andrew has 2 marbles, that is, x = 2

Then, 2x + 12 = 2(2) + 12

= 4 + 12 = 16

Thomas = 16 marbles
