OpenStudy (alexandervonhumboldt2):

with what?

sammixboo (sammixboo):

Tag me once you get your question posted @sammixboo =)

OpenStudy (anonymous):

Evaluate. |dw:1425428363402:dw|

sammixboo (sammixboo):

First subtract 3 - 9, which is?

OpenStudy (anonymous):

-6?

OpenStudy (alexandervonhumboldt2):

yes

OpenStudy (anonymous):

okay.

sammixboo (sammixboo):

Yup! So now we have |dw:1425428677048:dw|

sammixboo (sammixboo):

Now we do what's in the other parenthesis, 8 - 2, which is?

OpenStudy (anonymous):

6.

sammixboo (sammixboo):

Right! so now we have \(\dfrac{6(5\times-6 - 1)+2}{7\times6+4}\) Now still doing what's in the parenthesis, what is \(5\times-6 - 1\)

OpenStudy (anonymous):

Wait a minute, I think there's a problem with the way I wrote it.

OpenStudy (anonymous):

One moment, please! :)

sammixboo (sammixboo):

Okie dokie! Tag me when you finish

OpenStudy (anonymous):

|dw:1425428918696:dw| This is what it is, on the problem, how it's written COULD make a difference.

OpenStudy (anonymous):

@sammixboo

sammixboo (sammixboo):

Yeah, it's the same way you wrote it above, hehe. Brackets [....] is the same as parenthesis (....)

OpenStudy (anonymous):

Okay, but the question that's bothering me is the in first equation. Is the 1 in the equation negative?

OpenStudy (anonymous):

@sammixboo

sammixboo (sammixboo):

No, it's subtracting 1, anyways, let's continue. We have this \(\dfrac{6(5\times-6 - 1)+2}{7\times6+4}\) Still working in the parenthesis, what is \(5\times-6 - 1\)? First multiply 5 and -6 then subtract 1

OpenStudy (anonymous):

-31

sammixboo (sammixboo):

Right! so now we have \(\dfrac{6\times-31+2}{7\times6+4}\) Now let's do all that multiplication in that problem. What is 6 times -31 and 7 times 6

OpenStudy (anonymous):

first one is -186 and the other one is, 42.

sammixboo (sammixboo):

Right! So now we have \(\dfrac{-184+2}{42+4}\) What's -184 + 2 and 42 + 4?

sammixboo (sammixboo):

I meant -186

sammixboo (sammixboo):

Not -184, sorry

OpenStudy (anonymous):

XD you just gave me the answer! First one is -184, and the other is 46

OpenStudy (anonymous):

@sammixboo

sammixboo (sammixboo):

Whoopsie xP

sammixboo (sammixboo):

Yes! Now divide -184/46

OpenStudy (anonymous):

goshdarnit! My original answer was so close yet so far! >:/ but anyway the answer is...four.

OpenStudy (anonymous):

My original answer was 4.04 :/

OpenStudy (anonymous):

I guess you could say, I made an ERROR Hahahaha!

OpenStudy (anonymous):

@sammixboo

sammixboo (sammixboo):

Hehe, anyways, the answer isn't 4. WHen dividing a negative by a positive, the answer will always be negative, so it's -4 :)

OpenStudy (anonymous):

oh right I got negative four sorry. I completely cut off the negative sign.

OpenStudy (anonymous):

@sammixboo I could still use your help though.
