-4 + x 2 + y
------- = 5 and ------ = 5
2 2
so x = 10 + 4 = 14 and y = 10 - 2 = 8
endpoint N = (14,8)
$ per min is a rate. you multiple by minutes to get dollars.
A = 10x
B = 5x + 20
set them equal to find minutes, x.
10x = 5x + 20
10x - 5x = 20
5x = 20
x = 4
Tim has 2 times as luke
t=2l
they have 29 goether
t+l=39
subsitute
2l+l=39
3l=39
divide by 3
l=13
subsitue
t=2l
t=2(13)
t=26
tim has 26 and luke has 13
I don't know how many marble Tim has but probably all of them since alll must die and then the marbles go to Time
A) 10s=2m
B) It would take 20 seconds for 4 miles
