Answer:
80 runners
Step-by-step explanation:
24/30=0.8
0.8*100=80
make a proportion: 30/100 = 24/x
cross multiply: 2400=30x
divide: 2400/30=80
6k(5f+3)
18k+30fk
Factor out 6.
6(3k+5fk)
Consider 3k+5fk. Factor out k.
k(3+5f)
Rewrite the complete factored expression.
9.57
2.57 + 1.7= 4.27
4.27 + 5.3 = 2.57
i think it's C
