Answer:
Prime numbers are whole numbers that has factors of 1 and itself.
Example: 2 is a prime because there is no way you could factor it except 1 and 2.
Composite numbers have more factors which also include 1 and itself.
Example: 50 is composite because it has factors more than 1 and itself.
5 is a factor of 50; 10 is a factor of 50.
So let's begin sorting.
<em>Prime: 7, 11, 31.</em>
Composite: 4, 8, 10, 27.

If there were 1000 sheets of paper, then the thickness of each sheet would be 1.875 in divided by 1000.
1.875/1000 = 0.001875
Since there are 500 sheets of paper, each one is twice as thick as 0.001875, so each sheet is 0.00375 inches thick. 0.015 is much greater than 0.00375, so it must be incorrect.
Answer: 15.7 (1 decimal place)
Step-by-step explanation:
The formula for the circumference of a circle is d(diameter) x π(pi).
The diameter of this is 5 so you would do 5xπ=15.7 (1 decimal place)
Answer:
See explanation
Step-by-step explanation:
You are given the equation 
1. Add 8 negative x-tiles to both sides of the equation to create a zero pair on the left side. The equation then will have form
2. Add 5 negative unit tiles to both sides of the equation to create a zero pair on the right side. The equation now is
3. Divide both sides by 3:
