Subtract 3 to get:
7k^2-6k=0
Clearly, we can factor out a k to find that:
k(7k-6)=0
If either k or 7k-6 is zero, the whole expression is zero, so our solutions are zero and 6/7.
Answer:1: no 2: They probably measured the speed and they added up all the points they got and divided it by the total number of points and it ended up with the mean, and average speed for the rider

Answer:
x=180 units
Step-by-step explanation:
C=R
13x+450=15.5 x
15.5x-13 x=450
2.5 x=450
25 x=4500
x=(4500)/25=180
