C=2r
divide both sides by 2
c/2=r
c=2pir
divide by 2pi
c/(2pi)=r
1) have others replicate your experiment and compare results.
2) "choose" at random. What ever it is that you have to select from, let it be chosen randomly.
3) use a computer to store, analyze and organize your data, a computer won't give you a biased response.
The two ys must be the same. Equate the two right hand sides.
-x + 10 = x + 2 add x to both sides.
10 = x + x + 2
10 = 2x + 2 Subtract 2 from both sides.
8 = 2x Divide by 2
x = 8/2
x = 4
Now solve for y
y = x + 2
y = 4 + 2
y = 6
Use the other equation to check it.
y = - x + 10
y = -4 + 10
y = 6

Answer:
To find Felicity's hourly rate you first want to find out how many hours she has babysat altogether. In order to do this we need to take 2*10=20
