Question

Jamaal spent x minutes today practicing his guitar and y minutes today on homework. If the total time he spent on both is 45 minutes or more, which inequality best represents his practice time?

x + y < 45
x + y > 45
x + y ≤ 45
x + y ≥ 45

Answer 1

**The inequality that best represents Jamaal's practice time is x + y ≥ 45, where x is the number of minutes Jamaal spent practicing his guitar and y is the number of minutes he spent doing homework.**

This format is more professional because it uses complete sentences and proper grammar. It also defines the variables x and y, which makes the inequality easier to understand.

Here is a breakdown of the sentence:

* The word "inequality" is used because the expression x + y ≥ 45 is an inequality.

* The word "best" is used because the inequality x + y ≥ 45 is the most accurate representation of Jamaal's practice time.

* The word "represents" is used because the inequality x + y ≥ 45 represents the total time that Jamaal spent practicing his guitar and doing homework.

* The word "where" is used to introduce the definition of the variables x and y.

* The variables x and y are defined as the number of minutes Jamaal spent practicing his guitar and doing homework, respectively.

I hope this helps!
