6:27

6:28

6:29

6:30

I subtracted 6:28 & 6:27 then 6:29 & 6:28 then 6:30 & 6:29. then added the numbers together.then divided them  by 3 to get 34488.6. then  by 60 to get hours which is 574.81  by  24 to get the days which are 23.95046297.I believe that the closer you get to 25 billion the faster it gets so I believe it will end on March 26 at  7:40 becuse it will get faster as it gets closer.

I think that khan academy helps and why don’t other teachers use it.I like to have the option to retake my test and get a better grade.

I think I should get an A because I have not gotten more than 1 B on a test. I can add and subtract negative numbers because 10+-5 = 5 and 10 – 3 = 13. if you multiply a negative number with a positive number it’s a negative number. I  think khan academy help a lot for me to learn for the test.

 

First you have to find the closest perfect squares which, are 8 and 9. We already know that 81 and 64 are the closet, so now  we need to find the middle. So I added 8.5 to 64 to find the middle which is  72.5 ,so we now can elmanate 7.1 , 7.2 , 7.3 ,7.4 ,7.5. Since 77 is closer to 81 we can elmanate 7.6 and 7.7. So it could 7.8 or 7.9

I thought the first test was hard until, I learned how multiply and divide negative numbers.
