For his long distance phone service, Brian pays a $5 monthly fee plus 9 cents per minute. Last month, Brian's long distance bill
was $11.93. For how many minutes was Brian billed?
2 answers:
5+.09m=11.93 subtract 5 from both sides
.09m=6.93 divide both sides by .09
m=77
So he was billed for 77 minutes.
5 + 0.09m = 11.93
0.09m = 11.93 - 5
0.09m = 6.93
m = 6.93 / 0.09
m = 77....Brian was billed for 77 minutes

4x + 6y = 30 can be an equation.
Meter is the best metric measurement.
Answer:
y=-3/5x+16
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(13-19)/(5-(-5))
m=-6/(5+5)
m=-6/10
simplify
m=-3/5
y-y1=m(x-x1)
y-19=-3/5(x-(-5))
y-19=-3/5(x+5)
y=-3/5x-15/5+19
y=-3/5x-3+19
y=-3/5x+16
