Sarah gets 5 community service hours for donating a coat. She also receives 2 hours for
each teacher she helps clean their
classrooms. If she needs a total of 25 hours
of community service, how many teachers
does she need to help to reach her
community service requirement?

10 teachers

Step-by-step explanation:

25 - 5 = 20 this leaves us with 20 hours left of community service hours, we then divided it by how many hours she get by helping a teacher to get 10. to verify if she helps 10 teaches that's 10 times 2, this gives us 20. then add the 5 hours from donating the coat to get 25

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
