dont you have to like turn the decimals into whole numbers in an eqaution to solve it?

3. anonymous

not necesarily

4. anonymous

okay thanks! :D

5. anonymous

hmm sorry i hope you dont mind, but how would you do that with a distributive problem?

6. anonymous

yeah thats what i was thinking, i've seen some people turn it into whole numbers i thought that was the way to do it

7. Ghazi

add 6.8 on both the sides

8. anonymous

yes i got it now ghazi :)

9. anonymous

why :(

10. anonymous

where is the other one ?

11. Ghazi

5.6h -6.8+6.8=43.27+6.8 5.6h=50.07 now divide both sides by 5.6 $\frac{ 5.6h }{ 5.6 }=\frac{ 50.07 }{ 5.6 }=8.94$ h=8.94 :)

12. anonymous

oh you mean the other question?

13. anonymous

ghazi is that distributive property now? or is it just normal ?

14. Ghazi

its just normal, you dont need to use distributive here , it is used only when there is something like this 5(x+3) = 5*x+5*3

15. Ghazi

@Luis_Rivera i am outta here bro :D keep it up ;)

16. anonymous

never mind guys, i will figure it out somehow, thanks for the help though :(

17. Ghazi

:) did you get it now ?

18. anonymous

yes i got that one now, i just need to know how to do the same just with the distributive property

19. Ghazi

post a question where you are supposed to use distributive law, you cant use distributive here, how could you when there is nothing to distribute

20. anonymous

haha :D well thats what im saying there is a problem similar to this one just have to distribute some stuff, hold on

21. Ghazi

alright :)

22. anonymous

1.4(u - 3.7) = 17.08

23. anonymous

lol

24. anonymous

is something funny?

25. Ghazi

now you have to go this way 1.4*u - 1.4*3.7 =17.08

26. Ghazi

you need to multiply 1.4 with the stuff inside bracket that is, you have to distribute 1.4 over u and 3.7

27. Ghazi

then it will be 1.4u-5.18 = 17.08 after that add 5.18 both sides, clear?

28. anonymous

huh :/

29. anonymous

so you add 5.18 to 17.08?

30. Ghazi

what , its simple, look this is what you have to do to distribute 1.4|dw:1363044693962:dw|

31. anonymous

22.26?

32. anonymous

oh okay i understand now :)

33. Ghazi

yes add 5.8 to 17.08, correct

34. anonymous

so thats it?

35. anonymous

nooo

36. Ghazi

sorry you are right

37. anonymous

:D

38. Ghazi

now you have 1.4u=22.26 divide each side by 1.4 , actually you have to take everything away from variable that is 'U' here

39. Ghazi

$\frac{ 1.4 u }{ 1.4 }=\frac{ 22.26 }{ 1.4 }$

40. anonymous

15.9?

41. Ghazi

right :)

42. anonymous

thanks :)

43. Ghazi

:D YW

44. anonymous

hmm can you check the one that i did today, ive done it all i just need someone to check it?

45. anonymous

ghazi :(

46. Ghazi

keep posting question and what you got finally , it can be checked now :)

47. Ghazi

i am here lol please post your question and the final answer that you got i can check all of them now :D

48. anonymous

|dw:1363045237404:dw|

49. anonymous

is that wrong? :(

50. Ghazi

amazing :D thats absolutely right :D

51. Ghazi

just write the question and then write what you got, finally , it can be checked easily :)

52. anonymous

how is it right? its not one of the options

53. Ghazi

is this your question , 13d-53=9d+19 ?

54. Ghazi

if yes then 13d-53=9d+19 subtract 9d both the sides 13d-9d-53=9d-9d+19 4d-53=19 now add 53 on both sides 4d-53+53=19+53 4d=72 divide both sides by 4 d=18 that is correct

55. anonymous

yes, as written above..

56. Ghazi

then you are right

57. anonymous

oh wait it is there, i was looking at a totally different question :/

58. Ghazi

damn lol
