Answer:
None
Step-by-step explanation:
This doesn't really make sense, If the item is 629$ and Keith only gives 50$ Keith is the one who should pay.
Keith should get $43.71
The answer is 43.71 because 50 minus 6.29 equals 43.71
y=3x
I took the test
(0,4)
f(x)=4-5x
4-5(0)
5(0)=0
4-0=4
use a calculator fo find the value
-45 - 9n = -81
-9n = -81 + 45
-9n = -36
n = -36/-9
n = 4
Hope this helps you. :)
