First line up and add together all of your whole numbers. 
7+8+4= 
Then add up all of your fractions. I like to set them up in columns one above the other. That way when you change the denominators you can see them easier.
looking at all the denominators we can see that they all have a 6 in common. So change them all to a 6, remember what you do to the bottom you have to do to the top. Multiply 2/3 top and bottom by a 2, Multiply 1/2 top and bottom by 3 and the last is 1/6 so you don't need to change that one. Now you can add all the tops together and end up with 8/6. This is improper divide the bottom into the top and you have 1 and 2/6 left over. This will reduce to 1 and 1/3. NOW go back and add this to the whole parts that you added up first. The final answer should be 20 and 1/3/

Circumference - Item 2838 Question 4 of 7
nevsk [136]
First, the formula of the circumference.

There are two formulas:
1. C = π*d
[Note: d = diameter]
2. C = 2*π*r
[Note: r = radius]
[Note: This symbol * means to multiply.]

Since we are given the diameter, it’s easier to use the first formula, π*d. Let’s not be too hard on ourselves.

Okay, so let’s state our decided formula:
C = π*d
Then replace d with the car tire’s diameter:
C = π*(32)
Afterwards, find a calculator and multiply π with 32. You will get 100.5309649 as result.

If where to round is stated in your question, round to that. If not, it’s best to round by two decimal places. In this case, we’ll round 100.5309649 to 100.53.

Please add your units as well. In this case, the final answer will be: 100.53 inches.

Since this is a word problem, don’t forget your final statement!

“The approximate circumference of the tire is 100.53 inches.”

B is a subset of A g Let set A = {a, b, c} and let set B = {b, c, d}<br> a. True <br> b. False
xxMikexx [17]

Answer:

False

Step-by-step explanation:

A subset is a set whose elements belong to another set

If B is a subset of A, B would contain elements of A

For example,  A = {a, b, c} and if B is a subset of A , B = { a, b}
