Question

Tess practices her flute for at least 10 hours per week. She practices for a half of an hour each session. If Tess has already practiced 4 hours this week, how many more sessions remain for her to meet or exceed her weekly practice goal? (Inequality format)

Answer 1

Tess needs to have 12 or more sessions to meet or exceed her weekly practice goal.

Step-by-step explanation:

To find out how many more sessions Tess needs to meet or exceed her weekly practice goal, we can use an inequality format. Let's represent the number of sessions with x. We know that Tess practices for a half of an hour each session and has already practiced 4 hours this week. So the total number of hours she needs to practice is 10. We can write this as the inequality 0.5x + 4 ≥ 10.

To solve the inequality, we first subtract 4 from both sides: 0.5x ≥ 6. Then, we divide both sides by 0.5 to isolate x: x ≥ 12.

Therefore, Tess needs to have 12 or more sessions to meet or exceed her weekly practice goal.
