Answer:
If this is the problem
g(t) = t2 - 3t and h(t) = 3t - 4
g[ h(t) ] = (3t-4)2 - 3 (3t-4)
g[ h(t) ] = 9t2 - 24t + 16 - 9t + 12
g[ h(t) ] = 9t2 - 33t + 28
(-3 1/3) / (4/9).....turn -3 1/3 to an improper fraction
(-10/3) / (4/9)...when dividing fractions, flip what u r dividing by, then multiply
-10/3 * 9/4 ...now just multiply
-30/4 or if u need it back as a mixed fraction, it is - 7 1/2
Answer:
I think they first one is .5 and I'm not sure on the other
The first evening she received x calls.
The second evening she received 7 fewer calls than the first evening, so she received x-7 calls.
The third evening she received 3 times as many calls as the first evening, so she received 3x calls.
Over the three evenings she received 73 calls altogether.

The first evening she received 16 calls, the second evening she received 9 calls, the third evening she received 48 calls.
