30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400
Answer: 400 zebras.
Answer:

Step-by-step explanation:
1) if to re-write the given equation into slope-interception form, then:

the slope of the given line is 5/2;
2) according to the rule of perpendicular, the required slope should be:
s*(5/2)=-1;
3) if to solve this equation (s*5/2=-1), then s=-2/5 or -0.4.
Okay so f(n) is the range and n is the domain. The graph should be inclined up crossing (0,0). The domin is (0, infinity) because is she woulds 0 hours then Julia will get paid $0 so it starts at 0 and goes to inifinity.
