The correct answer is 2 pi
So firstly, foil 3(4g + 6) and 2 (6g + 9): 
Now since the quantity is the same on both sides of this equation, this means that <u>this equation has infinite solutions.</u>
He can make 36 pies in a day because there are 24 hours in a day and
24/8=3
3•12=36
Convert the percentage into a number then divide it by the income.
When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1).
Hopefully my explanation was clear?
