The statement below describes a situation in which opposite quantities combine to make 0. Is the statement true or false? A mountain biker gets halfway up a hill and realizes he forgot his water, so he returns to his starting point. True False

|dw:1440607171841:dw| right?

6. anonymous

yes

7. amilapsn

So what do you think?

8. anonymous

true

9. amilapsn

Bingo!

10. anonymous

thanks! i have a bunch of more questions! cab you help?

11. amilapsn

hm... ok...

12. anonymous

ok :) thx!

13. anonymous

14. amilapsn

here also you can apply the mountain biker's logic...

15. amilapsn

first he deposites$$\rightarrow$$going uphill then withdraws$$\rightarrow$$returning back

16. amilapsn

So, what would be the answer?

17. anonymous

d @amilapsn

18. amilapsn

gotcha!

19. anonymous

The statement below describes a situation in which opposite quantities combine to make 0. Is the statement true or false? Jeremy spends $4 for breakfast and then spends$4 for lunch. True False

20. amilapsn

This is easy for you. I know you know the answer.. :)

21. anonymous

false

22. amilapsn

yep... climbing downhill and climbing downhill again

23. anonymous

@amilapsn

24. anonymous

@amilapsn

25. amilapsn

It's not clear

26. anonymous

ok im going to zoom in on each multiple choice

27. anonymous

@amilapsn

28. amilapsn

ok

29. anonymous

30. anonymous

@amilapsn

31. anonymous

32. amilapsn

hm...... I think now you can help me to figure out what's the answer dear :)

33. anonymous

no i dot know :(

34. anonymous

@amilapsn

35. amilapsn

remember our biker... Same logic applies here...

36. amilapsn

Here's the logic.: Start from zero. Going up means plus(+) Going down means minus (-) Got that?

37. anonymous

c?

38. amilapsn

yep

39. anonymous

@amilapsn

40. amilapsn

gains---> plus losses---->minuses right? So what do you guess?

41. anonymous

a

42. anonymous

@amilapsn

43. anonymous

@amilapsn

44. amilapsn

Very well done!

45. anonymous

@amilapsn

46. anonymous

@amilapsn

47. amilapsn

You know multiplying of mixed fractions right?

48. anonymous

yes

49. amilapsn

What you want to know is the sighn, ok?

50. amilapsn

*sign

51. anonymous

i got d

52. amilapsn

not quite...

53. anonymous

b sorry @amilapsn

54. amilapsn

yep!

55. anonymous

Without multiplying, determine the sign of the product (−247,634)(183,758). The sign of the product is positive because a negative multiplied by a positive is a positive. The sign of the product is negative because a negative multiplied by a positive is a negative. The sign of the product is negative because the first number is negative. The sign of the product is positive because the second number is positive.

56. anonymous

b?

57. anonymous

@amilapsn

58. amilapsn

yep...

59. anonymous

Multiply (3)(−4)(2). −48 −24 24 48

60. anonymous

b?

Marlon withdrew $25 from his savings account every week for 5 weeks. Which expression is the best choice to help him determine the total amount of money he withdrew? (25)(−5) = −125; he withdrew$125 (−25)(5) = −125; he withdrew $125 (−25)(−5) = 125; he withdrew$125 (25)(5) = 125; he withdrew \$125

65. amilapsn

yep you are correct....

66. anonymous

@amilapsn

67. amilapsn

withdraw means minus right?

68. anonymous

yes

69. amilapsn

So what do you think?

70. anonymous

a?

71. amilapsn

think again.... have you seen ..... ;)

72. anonymous

is it either b or c?

73. amilapsn

It can't be c, Can you say why?

74. anonymous

um i dont know

75. amilapsn

usually the terms cannot be minus values... they are always positive.... So 5 cannot be negative.... Got it?

76. anonymous

got it! so b?

77. amilapsn

hm.... yeah...

78. anonymous

@amilapsn

79. anonymous

@amilapsn

80. amilapsn

you can think it like this way: Here's also the bicycle logic $\Huge\sf\color{blueviolet}{a\star b}$ We always begin with zero... Let's think we are on the zero. first simply we go to the point a. For example if a=5 we walk to 5.. if it's -5 we walk to -5 Then we've to consider the $$\color{blueviolet}{\star}$$. It can be $$\color{blueviolet}{+}$$ or $$\color{blueviolet}{-}$$ if it's + we don't have to turn But if it's minus we have to turn back... Then we have to consider about b If its minus we move bakward the amount of b... let say b=-2.. then we move backward two units if b is positive we just have to move forward the amont. Got it....

81. anonymous

so what would it be

82. amilapsn

83. anonymous

ok

84. anonymous

a

85. amilapsn

yep....

86. anonymous

What number should be added to 17 to make the sum 0? 0 –16 17 –17

87. anonymous

d?

88. amilapsn

yep... !!

Use absolute value to express the distance between −10 and 16 on the number line. |−10 − 16| = −6 |−10 − 16| = 6 |−10 − 16| = −26 |−10 − 16| = 26

90. amilapsn

@ikram002p can you help her?

91. ikram002p

sorry have to do something =(

94. anonymous

@geny55 plz open new boards for new questions.

95. anonymous

TY. :)

96. anonymous

good luck on those questions

97. anonymous

thx
