Question

1. Gabe's age is one less than twice Mary's age, a. Write an expression
for Gabe's age.

Answer 1

G = 2M - 1

Explanation:

The phrase "one less than twice Mary's age" means we subtract 1 from twice (2 times) Mary's age.

Using G to represent Gabe's age, and "is" meaning =, we have G = 2M - 1.

Answer 2

Answer: 2a-1

Step-by-step explanation: 2 times Mary's age minus one is 2 times a minus 1, which is just 2a-1
