Question

Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing, which inequality represents this situation?

Answer 1

The inequality is y≥45x.

Answer 2

Required Inequality is y ≥ 45x.

Explanation:

Time Lionel play trumpet = 45 minutes

Given,

Number of days Lionel Practices = x

Total number of hours he spend practicing = y

We have to write the inequality satisfying the situation.

Total time he Practices the trumpet = 45 × x = 45x

According to the question,

Total number of hours he spend practicing ≥ Total time he Practices the trumpet

⇒ y ≥ 45x

Therefore, Required Inequality is y ≥ 45x
