Chelsea had made six of seventeen freethrow attempts. How many consecutive free throws must she make to raise her percentage of free throws made to exactly 50 percent?

Math 
Reiny,
(6+x)/(17+x) = 1/2
12 + 2x = 17+x
x = 5
check:
with 5 more successful throws she made 11 good ones
out of a total of 17+5 or 22
11/22 is 50%
