Answer:
64
Step-by-step explanation:
If the number is x we have the equation:-
3x + 5 = 197
Subtract 5 from both sides:-
3x = 192
x = 192/3
x = 64
1 hour = 60 minutes, so 3 hours = 3 * 60 = 180 minutes.
Her total time was 3 hours and 28 minutes, so 180 + 28 = 208 minutes.
Divide her total time by total miles run:
208 minutes / 26 miles = 8 minutes per mile.
F(n)=3n-2
Plug in 2 for n. f(2)=3(2)-2=4
THis equals the number of permutations of 4 from 6.
= 6P4 = 6! / (6 - 4)! = 6! / 2! = 720/2 = 360 answer
