Answer 2

The inequality is
`0.75x\geq y`

Explanation:

Given : 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.

To find : Which inequality represents this situation?

Solution : He plays trumpet for a minimum of 45 minutes

`45 \text{minutes}=(45)/(60)=(3)/(4)=0.75\text{hours}`

If x is the number of days that Lionel practices then he practices for at least

`=0.75x` hours

y is the total number of hours he spends practicing

So, the inequality form is:

`0.75x\geq y`

i.e, 0.75x is greater than y.
