Given:
The system of inequalities is


To find:
The values of a for which the system has no solution.
Solution:
We have,
...(1)
It means the value of x is less than or equal to 5.
...(2)
It means the value of x is greater than or equal to a
Using (1) and (2), we get

But if a is great than 5, then there is no value of which satisfies this inequality.
Therefore, the system has no solution for a>5.
Answer:

Step-by-step explanation:
Answer: 9
Step-by-step explanation:
In order to find the people out of the 150, we first multiply 9/25 and 150 together. This will give us the people who DO own a dog. This brings us to 54.
Now, if we multiply 54 by 1/6 we get the answer of 9, because 1/6 of the dog owners own a cat as well. We have now reached the desired amount.
