Answer:

Explanation:
Let x represents the number of hours spent practicing his backhand
Let y represents the number of hours practicing his serve.
Since we are given that Tim practices his backhand and his serve at least 2 hours each day i.e. he practices his backhand and serves for two hours or more than two hours
⇒ x+y≥2 --(a)
We are also given that He works less on his backhand than his serve
⇒x < y --(b)
And we are also given that he practices his serve more than 1/2 hour daily.
⇒ y > 1/2 --(c)
Thus the inequalities are :

Thus the Option C is correct .
