So here are a few rules with exponents that you should know:
- Multiplying exponents of the same base:
- Dividing exponents of the same base:
- Powering a power to a power:
- Converting a negative exponent to a positive one:
<h2>1.</h2>
Firstly, solve the outside exponent:
Next, convert the negative exponents into positive ones:
<u>Your final answer is 
</u>
<h2>2.</h2>
For this, just divide:
<u>Your final answer is 
</u>
<h2>3.</h2>
For this, convert all negative exponents into positive ones:
<u>Your final answer is 
</u>
For this you need to know your angles in parallel lines.
3y will equal 87 as they are opposite angles and opposite angles are equal.
So y = 87/3
We can use the knowledge that angles in a straight line (in parallel line diagrams) will add up to 180. Therefore we do 180-87= 93. Now we know 3x=93 because just like the first example they are opposite angles. Now we know x=93/3.
(I didn’t have a calculator on me so you’ll have to work out the final result. Also I recommend looking into angles in parallel lines. I tried my best to explain so I hope you understand the jist of what I was trying to say.)
To find 86% of 50, you do 50*.86 (because .86 is the decimal form of the percentage 86%)
50*.86=43 people
Hope this helps

Answer:
Each can costs $0.86
Step-by-step explanation:
We find the unit price by dividing the cost by the number of cans.
11.18/13 = 0.86
I hope this helped and please mark me as brainliest!
