Will someone help this e.coli victim with this algebra problem?

Asked by Dutchess_III (47052points) December 5th, 2010

I know this is easy, but I just can’t figure it out and I just want to go to bed, but finals are next Saturday.

The lesson is saying that x – 1.7 + 2x – 6.2 x -49.6 = 0
......................................... -4.9x -49.6 = 0

I don’t see how they’re coming up with the -4.9 in the second step.

Yeah – that seems wrong.

I get -3.2x -51.3. Although I don’t know if I’m reading that clearly. There may be some confusion about which is a minus, which is a negative, which is the variable, and which is the multiplication sign.

I get what @iamthemob gets too, the way I’m reading the problem

x – 1.7 + 2x – 6.2x – 49.6 = 0
(x + 2x – 6.2x) – (1.7 + 49.6) = 0
-3.2x – 51.3 = 0

I get it!!! There’s a typo!
x – 1.7 + 2x – 6.2 x -49.6 = 0 should be:
x – 1.7x + 2x – 6.2 x -49.6 = 0

That would give you -4.9x -49.6 = 0 in the second step.

I’m trying to find that question…thanks for answering, guys. Hang on~

Well, I can’t find it. But I’ll bet @worriedguy is right about the typo.
Let me look at it again…x – 1.7x + 2x – 6.2 x -49.6 = 0
.....
I’m still coming up with -5.9.
-1.7+2= .3
.3 – 6.2 = -5.9.

Finals on a Saturday? Brutal, man.

@Dutchess_III
It’s 1 – 1.7 + 2 – 6.2 = -4.9
You forgot the 1.

x is the same as 1x

BINGO!!!! Thanks soooooo much @worriedguy!!!
@sliceswiththings Yeah….I used to LOVE taking tests, but I am so dreading this one. I’ve got a 92% right now, but I’m just not bonding (For lack of a better word) with the algebra. For the first time in my life I understand people who say they hate taking tests. I understand why it makes them sick! I will never take an online math course again. Anything else, no problem. But not math. I mean…..the problem I had with the adding—geez. I was lost for 2 hours!! I just finally compensated by adding 1 to whatever my answer was, and it worked, but I didn’t understand why. But I do now.
I love you guys!

I don’t see what the algebra problem has to do with e.coli…could someone explain please?

Dutchess_III's avatar

Heh! Nothng, really @ChocolateReigns! I’m just a little sick (for real) and wanted some attention along with my Algebra help! :) AND, also, see, if it was something so simple and I was just missing it cuz I dumb, I could say “I missed it because I sick, not cuz I dumb!”

Hey guys…I missed it because I’m sick. See.

@Dutchess_III Ah ok that makes more sense! I need to pull something like that later today when I miss something right in front of my nose! (it’s inevitable!) All I have is a nasty cough, though. Very nasty, had it for a month.

Dutchess_III's avatar

Make it sound worse than it is @ChocolateReigns! It’s the internet! They won’t know!!

Dutchess_III's avatar

I really was a little sick, tho. I’M NOT LYING!!! Just today I’m starting to feel almost 100%. But Get Well cards are still welcome. Excuse me. I haveta go frow up again (send cards)

Dutchess_III's avatar
