Answer:
r(n)=3n-1
Step-by-step explanation:
Solve for c by simplifying both sides of the equation, then isolating the variable.
C=36.5
To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer
11,15,19,23
an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7
