## epicsalsa 3 years ago The ratio between two quantities is 2 : 7. If the second quantity is 9.9 kg, find the first. A) 34.65 kg B) 2.83 kg C) 2.2 kg D) 2.92 kg

1. epicsalsa

Hi again :D

2. epicsalsa

you there

3. zordoloom

Yep.

4. epicsalsa

Ok

5. epicsalsa

So whats this one!

6. zordoloom

Question is too vague.

7. epicsalsa

Mean to comfusing

8. zordoloom

I think it's A.

9. epicsalsa

Ratio of first quantity to second quantity is constant 2/7 = y/9.9, where y represents the first quantity The cross products of proportions

10. zordoloom

wait.

11. epicsalsa

This is what i can help on

12. zordoloom

It's b then.

13. epicsalsa

when i do it it gives me 2.82857

14. epicsalsa

and alot of wacky numberrs

15. zordoloom

Ya, It would be B

16. nubeer

Ratio 2 : 7 now we make the second side 1 as it's data is given so divide both sides by 7 2/7 : 1 now for second quantity 9.9 is given so multiply both sides with 9.9 9.9 * (2/7) : 1 * 9.9

17. epicsalsa

For the set of ratios, find the two that are proportional. 49 , 7, 45 182 26 160 A) 49/182 and 7/26 B) 7/26 and 45/160 C) 49/182 and 45/160

18. epicsalsa

19. zordoloom

I'll let nubeer take over from here.

20. epicsalsa

NUUU

21. epicsalsa

28. epicsalsa

For the set of ratios, find the two that are proportional. 49 , 7, 45 182 26 160 A) 49/182 and 7/26 B) 7/26 and 45/160 C) 49/182 and 45/160

29. nubeer

its A option 49/182 = 7/26

30. epicsalsa

Write a proportion that could be used to solve for the variable s. Then solve. 5 pounds of seed for 2000 square feet x pounds of seed for 1500 square feet A) 5/1500 = x/2000; 7.5 B) 5/1500 = x/2000; 8.5 C) 5/2000 = x/1500; 8.5 D) 5/2000 = x/1500; 3.75

31. epicsalsa

And this one

32. epicsalsa

You there

33. nubeer

it's C for this one. 5/2000 = x/1500 x = 3.75

34. epicsalsa

Yup

35. epicsalsa

i know this might be to much asking can you help me still?

36. nubeer

yeah sure.

37. epicsalsa

Thanks!

38. epicsalsa

Solve the proportion. y - 4 = y + 2 3 5 A) 12 B) 11 C) 13 D) 52

39. epicsalsa

Inbewtween

40. epicsalsa

the the nubmers

41. epicsalsa

are a fraction

42. epicsalsa

i got an idea

43. nubeer

hmm idea? and what is that/

44. epicsalsa

45. epicsalsa

There

46. epicsalsa

In the attachment is the question

47. nubeer

5(y-4) =3(y+2) open brackets and multiply 5y-20 = 3y +6 now just find the value of y.. can you?

48. epicsalsa

Ummm

49. epicsalsa

is it 3.25

50. nubeer

nop.. can you put steps so i can tell where u made mistake.,

51. epicsalsa

i jsut did the other you gave me

52. epicsalsa

jsut added the like terms

53. epicsalsa

added the 20 on both sides

54. epicsalsa

divided it

55. epicsalsa

gave me 3.5

56. nubeer

divided by?

57. epicsalsa

26

58. nubeer

noo.. let me explain 5y-20=3y+6 first add 20 on both sides.

59. epicsalsa

26

60. nubeer

5y = 3y +26

61. epicsalsa

ok

62. nubeer

now subtract -3y on both sides.

63. epicsalsa

2y

64. nubeer

yes so 2y = 26 now divide both sides by 2

65. epicsalsa

oh 13

66. epicsalsa

zordoloom is on :D

67. nubeer

yes.. :)

68. epicsalsa
