Kids Vs Time Married

Hypothises

I believe That the longer you are marriend the more kids you should have! Beacause you dont have three kids in 1 year.

Conclution

My hypothesis was incorrect. You can see from my gragh on my gragh and chart page that there was no corralaton on my gragh therefor it does not matter how long your parents have been married and how many kids they may or may not have. They do not have anything in common mathmaticly.

Although they do have unmathmatical things in common. It was actually very hard to get results sor this test. I could not fingd anyone with parrents without adivorce. Wich leads me to yet another question, does the number of years you are married effect how soon you get divorcede?

My Problems

1) n+ 19= (-46)

        -19     -19

            (-65)

2) 24-n=45

  +24    +24

        69

3)-14n=84

     __   __

   -14    -14

        (-6)

 4) n/-4=44

       x4    x4

       (-176)

How To solve Them

1) For problem one you need to do the opposite  of add 19 to (-46) and you need to take away nineteen. You should get (-65). That is your answer.

2) First like I said before do the oppisite of the known number in your problem (the awnser is not a part of the problem). Wich in this case is take away 24 from 45, so you need to add 24 and 45. You should get 69.

3) First you need to do the opposite of multiply (-14) by (-84), and divide it. You should get (-6).

4) Sence you are diveding (-4) by n in the problem you need to multiply (-4) by 44. You should ge (-176)

How To Unsolve

After you solve a question if you feel uneasy about your answer all you have to do is check it! To check it all you do is do the actual question. Like for example n+19=(-46). I said the answer was (-46) so just do (-65)+19=(-46). So your answer is right.
