13 more than twice a number

Question

Translate this phrase into an algebraic expression.

Answer 1

First, you want to pick a variable to represent the "number" in the problem. So, let's just say "number" is "n."

It states that the expression is 13 more than twice a number, so first let's represent twice a number:

2n

Now, put 13 more onto that piece just by adding 13:

2n + 13

Therefore, the algebraic expression is 2n + 13
