You basically need to set up a porporion:
1.6/2.4 = x/7.2
x=4.8
Answer:
<h2>y - 5 = -1/4(x - 4)</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

We have m = -1/4 and the point (4, 5). Substitute:

V1=50km/h
v2=90km/h
s1=s2=6km
s=12km
The average speed over the 12 km drive:
v=s/t
The time needed to drive 12km will be:
t = t1+t2
t1=s1/v1, t2=s2/v2
t=s1/v1+s2/v2=(s1v2+s2v1)/(v1v2)
v=sv1v2/(s1v2+s2v1)=12*50*90/(6*50+6*90)=64,28 km/h
Answer:
2x+2y=8
Step-by-step explanation:
If you calculate it would be 3hx/5
