Question
Write an inequality to represent this real-world situation. Andre wants to practice the piano 9 hours a week. Each time he practices he practices for 23 hour. If he has already practiced 2 hours this week, how many sessions, x , does he still need to practice to reach or surpass his goal?
The inequality that represents this situation is:
9 - 2 + 23x ≥ 9, where x represents the number of sessions Andre still needs to practice.
Simplifying the inequality:
7 + 23x ≥ 9
Therefore, Andre still needs to practice a minimum of 1 session to reach or surpass his goal.
