Answer:
The charge per day is $25 and the charge per mile is $0.35
Step-by-step explanation:
Let
x -----> the charge per day
y ----> the charge per mile
we know that
3x+200y=145 -----> equation A
5x+430y=275.50 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system is the intersection point both graphs
using a graphing tool
The intersection point is (25,0.35)
see the attached figure
therefore
The charge per day is $25 and the charge per mile is $0.35
Answer:
I think it's 116.3, 133.8, 167,6
Step-by-step explanation:
Set up a table.
Pages | Minutes
-----------------------
25. | 30
? | 200
One way is to cross multipy.
200 x 25 = 5,000
30 x ? = 5,000
So do 5,000 divided by 30 and you get your answer
Answer:
is sometimes positive and sometimes negative.
Step-by-step explanation:
Take
Take
Hence for and for
So is sometimes positive and sometimes negative in the interval.
