Answer:
gh = x+9
Step-by-step explanation:
H is the number of hours Miguel could practice the piano each week.
Miguel goal is to practice the piano more than x hours per week.
h >= x
hence depending on the amount ot hours needed to practice each week, you have to set them to be the minimum, and any other larger quantity satisfies the proposition as well.
8 batteries = $10
6 batteries = x
x = cost of 6 batters in dollars
Step: cross multiply
8x = 10*6
x = 60/8
x = 7.5
6 batteries cost $7.5
The positive square root is 0.5
