Answer:
There are 10 dogs in the kennels
Step-by-step explanation:
The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.
Which means, if 
the number of dods and 
is the number of cats, then,
Given that there are 20 cats, so 
Now, from equation (i) we have,
.
Hence, there are 10 dogs in the kennels.
Answer:
-35-18x
Step-by-step explanation:
just calculate the difference
-35-20x+2x
-35-18x
The expression g - 7 is the answer.
Because there are 7 more girls than boys, b = g - 7.
The solutions are where the quadratic is equal to 0, or when the quadratic crosses the x axis.
Where the quadratic crosses the x axis are the solutions:
6) x = –5, x = –6
7) x = 0, x = 1
8) x = –6, x = 1
9) x = –4, x = –3
