## me5050 Group Title Can someone confirm my answer for me? i feel like im wrong one year ago one year ago

1. me5050 Group Title

When you simplify each side of the equation 4(x + 3) = 5 – (x + 1), you will get the equivalent equation 4x + 12 = -x + 4.

2. me5050 Group Title

i pick true

3. tkhunny Group Title

It is not good that correct mathematics is followed by "feel like". If you are sure of your procedure, if you made no error, let's skip the feelings and be confident in the answer. Did you get it right or not?

4. me5050 Group Title

i really think it is true

5. tkhunny Group Title

That's a start. Now, is it or isn't it? Did you make any errors?

7. FirstFrostByte Group Title

Its true. :)

8. me5050 Group Title

:) see i got the same work you doo now i feel confident in myself lol

9. me5050 Group Title

can anyone help me solve 1/5n-12=-3? solve for n. I want to learn how to do this

10. tkhunny Group Title

That's the spirit.

11. FirstFrostByte Group Title

Okay one second.

12. tkhunny Group Title

Do you mean $$\dfrac{1}{5n}$$ or $$\dfrac{1}{5}n$$?

13. me5050 Group Title

the second on that you put

14. FirstFrostByte Group Title

Oh.. Okay one sec.

15. tkhunny Group Title

What's stopping you from Adding 12 and multiplying by 5? You're not "feeling" that it would be wrong, are you?!

16. me5050 Group Title

give me one second to see hang on

17. FirstFrostByte Group Title

$1/5 n - 12 = -3 \rightarrow witch means \rightarrow n/5 - 12 = -3 \rightarrow so \rightarrow n/5 -12 + 12 = -3 + 12 so n = 45.$

18. FirstFrostByte Group Title

Crap it got cut off :( N = 45.

19. me5050 Group Title

do you feel like helping me on a few more? if not its cool...

20. FirstFrostByte Group Title

n - - 12 + 12 = -3 + 12 5 So: n - = 9 = N = 45 5 Sure.

21. me5050 Group Title

ok give me a sec, im gouing to see if I can do them real quick

22. me5050 Group Title

@zzr0ck3r ;) im just not good at math...

23. me5050 Group Title

Solve the combined inequality and select the answer that best describes the graph of the solution. 3x – 7 > -10 and 5x + 2 < 22

24. me5050 Group Title

a.)open dot at -1, open dot at 4, and shaded between the numbers b.)closed dot at -1 and 5, shaded between the numbers c.)closed dot at 1, open dot at 5, and shaded between the numbers d.)none of the above

25. foxyhotty1 Group Title

4x+12=5-x-1 4x+12=4-x 5x=-8 x=-8/5 <---- answer

26. me5050 Group Title

so then the answer would be "none of the above"

27. amistre64 Group Title

make sure the question posted is correct

28. amistre64 Group Title

linear equations should either have no solution or one solution

29. me5050 Group Title

Solve the combined inequality and select the answer that best describes the graph of the solution. 3x – 7 > -10 and 5x + 2 < 22 a.)open dot at -1, open dot at 4, and shaded between the numbers b.)closed dot at -1 and 5, shaded between the numbers c.)closed dot at 1, open dot at 5, and shaded between the numbers d.)none of the above

30. amistre64 Group Title

ahhh, i was reading the first posted and not seeing how it correlated to this one

31. amistre64 Group Title

tell me what you got for your solution to chk with

32. me5050 Group Title

ok hang on im still trying to solve it. give me on more sec

33. me5050 Group Title

i got x>-1 or x<4 so i would choose A for my correct answer?

34. amistre64 Group Title

i agree

35. amistre64 Group Title

but hold on

36. me5050 Group Title

ok thankyou... i have one more and this one is a bit trickey there are several parts to it...would someone mind helping me out? I would like to know how to do thiss

37. amistre64 Group Title

ok, it says AND so that is correct

38. amistre64 Group Title

post it up

39. me5050 Group Title

ok give me one second :)

40. me5050 Group Title

A.) 2(x – 4) + 5x = -22 B.)2(x – 3) – 17 = 13 – 3(x + 2) C.)2/3X+6=10 D.)|2x + 4| = 10 E.)Solve for y: 2x – 3y = 6 F.)The sum of three consecutive EVEN integers is 42. What are the integers? (Name all three integers.) G.)Solve the inequality: -2x – 6 < 4. Be sure to provide the solutions, describe the circles and the shading for the graph. H.)Please solve the combined inequality and describe the graph. 3x-6 > -3 and 3x-6 < 12

41. me5050 Group Title

each letter is a seperate question.

42. amistre64 Group Title

thats not "one more"; thats several more :/

43. me5050 Group Title

I didnt realize that they were seperate, until i started to read them. if you cant help, then its cool...

44. amistre64 Group Title

I think F might be the only one that you might not be familiar with

45. me5050 Group Title

thankyou

46. amistre64 Group Title

can you think of a general set of 3 consecutive numbers?

47. amistre64 Group Title

consecutive even numbers that is

48. me5050 Group Title

4,5,6?

49. amistre64 Group Title

every even number is a multiple of 2 2*1=2 2*2=4 2*3=6 2*4=8 .... 2n = even integer

50. amistre64 Group Title

if we want 3 consecutive even integers; we could write it like this: 2n-2, 2n, 2n+2 to add these up we have 2n-2 + 2n + 2n+2 = 3*2n = 6n for what value of n does 6n = 42 ??

51. me5050 Group Title

7

52. amistre64 Group Title

good, then our middle number has to be 2*7=14 12+14+16 = 42 right?

53. me5050 Group Title

yes, i just got that! :) thankyou!! could u help me on G? and i promise thats it lol

54. amistre64 Group Title

Solve the inequality: -2x – 6 < 4 got tell me what you

55. amistre64 Group Title

56. me5050 Group Title

x<5

57. me5050 Group Title

-5*

58. amistre64 Group Title

lets chk -2x – 6 < 4 +6 +6 ----------- -2x < 10 /-2 /-2 ------------ x > -5 ; remember what the negative does to us

59. me5050 Group Title

shoot i did forget that lol, thanks for remidning me

60. amistre64 Group Title

open or solid, which would you pick and why?

61. me5050 Group Title

and i got x<6 for the other one open

62. amistre64 Group Title

there is no other one on G and open is correct; why open?

63. me5050 Group Title

crap see my ADD is messing me up!!! haha, im sorry!! but open because its what it equals?

64. amistre64 Group Title

if we see what the question is asking for > or < these notations have no "=" associated with them; a closed circle represent the "=" part

65. amistre64 Group Title

no equal, no solid

66. me5050 Group Title

ohhh that makes sense

67. me5050 Group Title

i didnt know that

68. amistre64 Group Title

x > -5 ; no equal, no solid <----0========> -5

69. me5050 Group Title

thankyou!!!!
