Answer: a. 5^42 and b 9a^6
Step-by-step explanation:
a. (5^3+4)^6
(5^7)^6 = 5^42
Amount left in account after paying for music class = $87.60 - $25.60 = $62
Amount in the bank account after 10 months = $62 x 10 = $620
Amount spent to go to the summer camp = 1/4 x $620 = $155
Before you do anything, you convert 1/4 into 0.25. Then you start multiplying. If you don't understand email me at

Answer:
x is the price the helmets were sold at.
y is the business expenses.
r is the revenue.
500x - y = r
Step-by-step explanation:
500x - y = r
We multiply x, the price that the helmets were sold at. Then we subtract y, which is the business expenses. After this, we get r, our revenue.
Equation; y=27x+405Step 1: Flip the equation.<span><span><span>27x</span>+405</span>=y</span>Step 2: Subtract 405 from both sides.<span><span><span><span>27x </span>+ 405 </span></span>= <span>y
<span> -405 −405</span></span></span><span><span>27x</span>=<span>y−405</span></span>Step 3: Divide everything by 27.<span><span><span><u>27x</u> </span></span>= <span><span><u>y − 405</u>
</span>27 27 27</span></span><span>--- dividing by 27 will isolate x which is the goal of solving the equation---
x=<span><span><span>127</span>y</span>−15
</span></span>Answer:<span>x=<span><span><span>127</span>y</span>−<span>15</span></span></span>
