Hello!
to find the percent of a whole, use this equation here:
(remaining) / (total) = X
X * 100 = %
in this case:
12 / 15 = 0.8
0.8 * 100 = 80
your answer is 80%
I hope this helps, and have a nice day!

Step-by-step explanation:
When you see that something is to the power of a negative number, it is another way of saying 1 over.

Answer:
4x + 9. Given f(x) = 2x + 3 and g(x) = –x2 + 5, find (g o g)(x). (g o g)(x) = g(g(x)) ... Given f (x) = sqrt(x) and g(x) = x – 2, find the domains of ( f o g)(x) and (g o f )(x). Since f (x) involves a square root, the inputs have to be non-negative. ... Given h(x) = (x + 1)2 + 2(x + 1) – 3, determine two functions f (x) and g(x
Step-by-step explanation:
for the first one set 3y+y=180 and y+x=180
the second one set w+y=180, 42+x=180, y+20=180, and 87+v
