Answer:
three and one fourth + 2x ≥ 6
Step-by-step explanation:
Let
x -----> the minimum number of hours he needs to practice on each of the two days
we know that
needs to spend at least seven hours each week practicing the drums
so

Convert mixed number to an improper fraction

substitute

Subtract 13/4 both sides


Divide by 2 both sides

therefore
The minimum number of hours he needs to practice on each of the two days is 
-2/3 is the answer bc you divide both by two and it simplifies
