Step-By-Step Explanation:

Answer A:the number of students who watch 6 to 9 hours of TV
Step-by-step explanation:
Just took the test.
Answer:
11.11 hours
Step-by-step explanation:
Rita = 20 hours
Neha = 25 hours
Let the time that they can complete the work together be written as x
1/20 + 1/25 = 1/x
Lowest Common Denominator is 500
25 + 20/500 = 1/x
45/500 = 1/x
Cross Multiply
45x = 500
x = 500/45
x = 11.111111111 hours
Approximately = 11.11 hours
Therefore, it would take Rita and Neha 11.11 hours to complete the work together.
