<h3>Answer: 33</h3>
=====================================
Work Shown:
8^(x+7) = 32^(x-9)
(8)^(x+7) = (32)^(x-9)
(2^3)^(x+7) = (32)^(x-9) .... replace 8 with 2^3
(2^3)^(x+7) = (2^5)^(x-9) .... replace 32 with 2^5
2^(3(x+7)) = 2^(5(x-9)) ... multiply exponents
3(x+7) = 5(x-9) ...bases are the same, exponents are the same
3x+21 = 5x-45
21+45 = 5x-3x
66 = 2x
2x = 66
x = 66/2
x = 33
Answer:
M and n are both negative
Step-by-step explanation:
m x n = c
mx + nx = bx
If b is negative, then we know at least M or N has to be negative.
But since C is positive and we know one has to be negative that means that the other also has to be negative because 2 negatives multiplied equal a positive

Answer:
$16.05
Step-by-step explanation:
The question has been kind enough to provide the solution to you! It suggest multiplying her sales by 0.3 to find 30% of the total, in order to find how much money she donated to charity. To put this into practice:
