I bet you mean n right?

3. anonymous

yes. that is what I said uptop "solve for n:"

4. freckles

oh I see "solve for N"

5. freckles

lets look at teh left hand side $(10+\frac{5}{8}+3+\frac{5}{8})+2+\frac{3}{8} \\ (10+3+2)+(\frac{5}{8}+\frac{5}{8}+\frac{3}{8})$ can you add 10 and 3 and 2 together?

6. anonymous

of course lol 15

7. freckles

ok can you add 5/8 and 5/8 and 3/8?

8. freckles

$15+(\frac{5}{8}+\frac{5}{8}+\frac{3}{8})=n+12$

9. freckles

hint you already have the same denominator

10. anonymous

yes and that equals ..I got 1.625 or 1.6

11. freckles

you only have to add the numerators (5+5+3)/8

12. freckles

oh I guess we can write in fraction form later I was trying to keep it in fraction form because the choices are written as fractions but we can go to decimals if you want then write as fraction

13. anonymous

I don't care :)

14. freckles

you don't want to write 1.6 that is an approximation

15. freckles

1.625 is correct though

16. freckles

$15+1.625=n+12$

17. anonymous

I thought before that the answer was B

18. freckles

well let's find out... can you add 15 and 1.625?

19. anonymous

16.625

20. freckles

and then subtract 12 on both sides

21. freckles

$16.625=n+12 \\ 16.625-12=n$

22. anonymous

16.625-12? 4.625

23. freckles

yes 16-12 =4 so 16.625-12=4.625 so if the directions was to "solve for n" you would say 4.625 and there is only one choice above that says 4 and something if the directions say "solve for N" you would say none of these but as you said you meant to say "solve for n" :p

24. anonymous

so 4 5/8? C

25. freckles

yes that does say 4 and something

26. freckles

5/8=.625 so 4+5/8=4.625

27. freckles

any questions?

28. anonymous

no thank you but thanks!1 very much for the help
