Basically plug in 2 where y is and 5 where X is
3(5)(2) - 4(2) , the parentheses are there to multiply
30-8
22
R=fixed rate
m=rate of miles
n= miless
T(n)=total amount per miles(n)
T (n) =mn+r
Answer:
2.5 hours
Step-by-step explanation:
Divide the travelled miles by the amount of hours to get the travelled miles for one hour. (17 miles in 1 hour) Then divide 42.5 by 17 to get the amount of time it takes to go 42.5 miles. (42.5 miles in 2.5 hours)
Hope this helps!
