If you're not sure then it probably won't help me.:p

\[3(-3+1)\]

4. VinnyT

-6

That's equal to -6. Enter 3(-3+1) on a calculator

Yeah.

You just substitute in.

8. VinnyT

Correct. :D Thanks man.

YW...

10. VinnyT

Do you know this one?

Which one?

12. VinnyT

7m + 2n - 8p over n for m = -4, n = 2 and p = 1.5

13. DLS

7(-4)+3(2)-8(1.5)

Looks like DLS is helping you.

15. VinnyT

-34 is what I got.

17. VinnyT

Oh...let's see.

7*-4+2*2-8*1.5/2

No, it's B.

22. VinnyT

It was B.

Enter 7*-4+2*2-8*1.5/2 in a calculator to check it...

Yes.

25. VinnyT

58. VinnyT

|dw:1370242006729:dw|

You're supposed to subtract?

60. VinnyT

Simplify.

Oh.

Hang on one moment.

63. VinnyT

Alright man.

It's A.

65. VinnyT

Correct. Alright this one. Sorry for asking so many questions! You made two deposits to your bank account this month. One deposit was \$24.61, and the second deposit was \$16.49. Your balance at the end of the month is \$72.31, and you made no withdrawals. Write and evaluate an expression for your balance at the beginning of the month. A \$72.31 + (\$24.61 – \$16.49); \$80.43 B \$72.31 – (\$24.61 – \$16.49); \$64.19 C \$72.31 – \$24.61 – \$16.49; \$31.21 D \$72.31 + \$24.61 + \$16.49; \$113.41

That's a long one....hang on.

A little help, @Kitt020912 ?

68. VinnyT

Alright.

Dude ,why are you cheating ?

70. VinnyT

I'm not. He's actually helping me tbh.

71. Kitt020912

She*

72. VinnyT

I didn't know that.. She*

Yeah hard to believe I'm helping for once in my OS life.

74. Kitt020912

I'm not good with word problems, sorry. :l

I can't see any help here .. you should learn how to answer the questions by yourself .

76. Kitt020912

If you know the setup, then I can help you from there.

77. Kitt020912

Eyad, why aren't you an ambassador? You act like one sometimes. c:

Anyway , Since there is no withdraw if you subtract the two deposits from the balance at the end of the month, you'll have the beginning balance.

@Kitt020912 i'm just using logic :)
