X=-7 divide both side by 3. Any expression divided by itself equals 1. Dividing a positive and a negative equals a negative. Calculate the quotation. Then you get X=-7
Answer:
a^9*b^6
Step-by-step explanation:
a^(-8) b 1 1
-------- = a^(-3), and ----------- = --------- Their product is --------------
a^(-5) b^(3) b^2 a ^3*b^2
This is the algebraic expression inside the parentheses. We must now take
the negative 3rd power of this result.
(a^3*b^2)^3 = a^9*b^6
Take a picture of the problem on PhotoMath and it will break down all of your steps.
He has replaced the pitcher 25 times and won 11 times.
Winning percentage = 11/25 = 44%
He kept the starting pitcher in 15 times and won 7 times.
Winning percentage = 7 /15 = 47%
There is a 3% higher chance they would win by replacing the pitcher.
The answer should be C.
