Well for what I understood...
Let's say...
10 Pigs in total... Horses is 2 times more than pigs so
20 Horses in total... Cow is 4 times more than horses so
80 Cows in total...
The numbers are just examples of what I sort of understood.
12.
Distribute the negative
2x - 5 - 9y + 8 + 16y
Simplify
2x + 7y + 3
13.
Square is 4 sides, all sides are equal
4 ( 4x + 3)
16x + 12

C.) 30h = 180
Since you already have your base all you have to do is find the height
BxH= A
30xH = 180
815 x 360 = 293,400 gal per second.
293,400 gal ÷ 4 quarts = 73,350 quarts per sec.
I'm fairly certain that's right - someone correct me if I'm mistaken.
Answer:
True
Step-by-step explanation:
First, we need to recognize that

Now, we can try to solve

Multiply each side by 

As we end up with an answer that cannot be true, we know that there is no solution.
Another method to solve this would be graphing the function 
When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.
