Answer:
59.049%
Step-by-step explanation:
J. J. Redick is an excellent free throw shooter and makes 90% of his free throws
P(making one free throw) =90%
Therefore:
We can distribute
2(5)+2(-x)=10-2x
we get
8+10-2x=?
18-2x=?
whatever that ? is, we don't know
multiply both sides by -1
2x-18=-?
add 18 to both sides
2x=18-?
divide bth sides by 2
x=9-(?/2)
whatever the left side it, just divide it by 2 and subtract it from 9
