Question

Winnie weighs 135 pounds and wants to wrestle in a larger weight class. She needs to gain x pounds to be at least 142 pounds. Write an inequality that can be used to all possible values of x, for Winnie to be at her goal weight.

Answer 1

135 + x ≥ 142

Explanation:

• Let's define the variable x as the number of pounds Winnie needs to gain.

• Since Winnie wants to weigh at least 142 pounds, we can write the inequality:

135 + x ≥ 142

This inequality states that Winnie's current weight of 135 pounds, plus the number of pounds she needs to gain (x), should be greater than or equal to 142 pounds.

• By solving this inequality for x, we can find all possible values that will allow Winnie to reach her goal weight.
• Solve:

x ≥ 142 - 135

x ≥ 7
