57.29 you do 48.55 times .18 which =8.74 then add the tip with the initial cost 8.74+48.55 =57.29 to get your answer 57.29
Answer:
your didn't give any proper point ,but i assuming the the question as
the line pass through the point (1,0,-2)
so answer is
(x-1)/a = y/b = (z+2)/c,
where a,b,c are constant
Step-by-step explanation:
Distance = (rate)(time)
In this problem, note that both girls traveled the same distance.
Karens distance = r * 1.5 hrs we dont know her rate
Nancy distance = 50 * 1 hr we know she started 30 min later
but arrived at the same time
since the distances are equal
r*1.5 = 50 * 1 all you have to do is solve for r
1.5r = 50
r = 50/1.5
r = 33 1/3 miles per hour
There are many equations that has a constant of
proportionality, might want to make it more specific.
