Answer:

Step-by-step explanation:

Start by factoring out a 5:

We need to find two integers that have a product of 12, and a sum of -7:
(-3)(-4)=12
-3-4=-7
We can split -7x into -3x and -4x

Factor each half separately:
![5[x(x-3)-4(x-3)]](https://tex.z-dn.net/?f=5%5Bx%28x-3%29-4%28x-3%29%5D)
Since x and -4 are both being multiplied by x-3, we can combine them:

19) 48 alligators; 7/8 of the alligators were asleep. How many were not asleep?
8/8 - 7/8 = 1/8
48 * 1/8 = 48/8 = 6 alligators were not asleep.
20) 2/3 of the student population participated. 1,500 is the student population of the school. HOw many attended the bike rally?
1500 * 2/3 = 1500*2 / 3= 3000 / 3 = 1000 students attended.
21) 18 times at bat:
Kayla 5/6 of the time = 18 * 5/6 = 18*5 / 6 = 90/6 = 15 hits
Tia 8/9 of the time = 18 * 8/9 = 18*8 / 9 = 144/9 = 16 hits
Tia got more hits.
