1. just_one_last_goodbye

Graham sold 6 magazines less than double what Adrianne sold, a. Which of the following expressions represents Graham's sales? A. 6a − 2 B. 2(a − 6) C. a2 − 6 D. 2a − 6

2. anonymous

So what would represent what Adrianne sold, if she was represented by the variable a

3. just_one_last_goodbye

I think A isn't it since 6 isn't what Adrianne got only graham

4. anonymous

Yes so double what Adrianne sold means 2a

5. just_one_last_goodbye

so D?

6. anonymous

Now what would it mean if Graham sold 6 mags less than 2a

7. anonymous

Yes

The points earned by each choir team during the All-State Competition are as follows: Choir Choir A Choir B Choir C Choir D Points 129.5 130.1 130.8 129.8 If points are reported by rounding to the nearest whole number, which team has a different score? Choir A Choir B Choir C Choir D

15. anonymous

Alright so we round up by 1 whole number if the decimal is 0.5 or greater. So what would Choir A be when rounded?

16. anonymous

And if the decimal is less than 0.5 than the whole number stays the same but the decimal becomes .0

17. anonymous

Based on that could you list what Choi A, B, C and D become when rounded?

18. just_one_last_goodbye

Alright lets see 129 130 131 130

19. anonymous

Not quite 129.5 also becomes 130 since it has 0.5

20. anonymous

So which one is different?

21. just_one_last_goodbye

oh sorry they taught me in second grade to just go back to the begining number

22. anonymous

That's fine, that only happens if it is less than 5

23. just_one_last_goodbye

I see so... whats the next step?

24. anonymous

Now which choir has a different score?

25. just_one_last_goodbye

first one since the others are in the 30's correct?

26. just_one_last_goodbye

oh wait sorry XD forgot... it is a 30

27. just_one_last_goodbye

so 131? which is Choir c?

28. anonymous

Yes, good job!
