a circle is divided into 18 equal parts how many degrees is the angle for each part? how many degrees is the angle for 5 parts? explain

Answers

Answer 1
Answer: There are 360 degrees in a circle, and we have 18 pieces, so we need to see how many times 18 goes into 360. We can find this out by dividing.

360/18=20

You can check this by multiplying 20 and 18 (it equals 360)!

So, each fraction of the circle will be 20 degrees.

If you take 5 of these 20 degree pieces, you'll need to multiply them by 20 to see how many degrees they'd be.

You need to multiply by 20 because each piece is 20 degrees, and we need to find how many degrees 5 pieces is. It's the same as doing
20+20+20+20+20! :)

20*5=100. 5 parts will be 100 degrees.


Hope I helped! :)

How do you do equations on both sides.

Answers

If you give an example of a problem you are having trouble with, I can help walk you through it.
hello , to do equation on bother sides; these are the steps i use personally
e.g. 
5x-4=2x+14
you would subtract 2x from both sides so it will simply to...
3x-4=14  (do the opposite to the 4 in this case it is subtract and the opposite is add so you would add 4 to the 14 as following)
3x=14+4 
3x=18 
(divide 18 by 3 )
x=6

PLEASE HELP THERE A FEW QUESTIONS THAT I NEED HELP I BEG YOU I NEED HELP

Answers

the first one is A. because it can all be divided by 4 and when you divided it also the exponents are subtracted.

second one is B. this one can be simplifide by doing the F.O.I.L. trick.

and last one is B also. because it's the only one that has a logic answer. if you were to F.O.I.L. it it would give you the answer but if you were to F.O.I.L. the others then you will find out the others don't add up.

 hope this can work.
The answer of the first question is the FIRST one which is
