andre wants to practice the piano 9 hours this week. each time he practices, he practices for 2/3 hour. If he has already practiced for 2 hours this week, how many sessions, x, does he still need to practice to reach his goal.
Make a Inequalities equation
Let x be the number of additional sessions Andre needs to practice.
2/3x is the total time Andre still needs to practice.
We want 2 hours + 2/3x hours to be less than or equal to 9 hours.
2 + 2/3x ≤ 9.
