Algebra - anyone?

[LindaC781]

I have to take College ALgebra - anyone take this? Can I ask some of you questions if I have any?

[LindaC781]

Just wanted to add - I need to pass this class with an A (nothing less will do) then I can apply to Radiology Tech school....

What would you like to know? All I gotta say it's intense..! Very time consuming....

I went through college math hell almost 20 years ago and I can't remember one single thing, lol. Good luck to you! :)

[ladyinhislife]

of all the maths i encountered in my 4 years in colege... this is the easiest...

[suzynyc]

Actually, when I progressed from Algebra to calculus, I found calculus much easier. I was surprised by that. But you must know algebra very well in order to do calculus. Ugh, I hope never to read a math formula again!

[Emerald]

I loved Algebra in secondary school. Favourite part of Maths!

[LindaC781]

Okay, I officially hate Algebra. Don't ask.

[Nirvana]

Isn't Algerbra famous for being something you're never gonna use

[Severus Snape]

That's a dirrrrrttttyyyyy word in my eyes!! I avoid algebra like the plague! xP
Yet, somehow, I passed it. Go figure lol.

[HumanNatur3]

Algebra was my favorite out of all the Math classes I took in College. Shoot me a message me if you have any questions and I'll try my best to help you.

[ArabianGirl~AllTheTime]

On behalf of all Arabs in this world, I sincerely apologize for bringing this horrible, HORRIBLE subject to existence! Please forgive us!!! :doh:

[bubbyduck4MJ]

Lol I hated it. and don't remember how to work it out =P

[artik]

I loved it :) Geometry was my favorite part of math, though.
I believe that every discipline can be made fun and interesting to learn. It depends on the teacher.

[LindaC781]

On behalf of all Arabs in this world, I sincerely apologize for bringing this horrible, HORRIBLE subject to existence! Please forgive us!!! :doh:

Oh My God!! It was YOUR fault after all!! LOL!!

[LindaC781]

Ok, I have just about had it with algebra. My dilemma? Try to set up 3 equations for the following word problem:

A basketball team sells tickets that are $10, $20 and VIP tickets that are $30. The team has sold 524 tickets overall. The team sold 191 more $20 tickets than $10 tickets. The total sales were $9370. How many tickets of each kind have been sold?

I think I need to set up 3 equations:

a = $10 tickets
b = $20 tickets
c = VIP $30 tickets

a + b + c = 524
10a + 20b + 30c = 9370

I am lost as to the third equation. Is it "a + a + 191 + c = 524"? Help me. I am stuck on this one.

After I set these up I do the 6 step solving...but I just need help knowing what the 3 equations are.

Linda

I am personally buying you a six-pack, whoever can help me out with this first!! No kidding!!!http://sphotos.ak.fbcdn.net/hphotos-ak-snc4/hs018.snc4/34258_10150222742865082_804520081_13405837_4594080 _n.jpg (http://www.facebook.com/photo.php?pid=13405837&op=1&view=all&subj=406381074811&aid=-1&auser=0&oid=406381074811&id=804520081)

[LindaC781]

No takers yet?? Scared ya off, did I? Got a nice pack of Coors waitin for ya, if you can help me. I'd even fly over to wherever the heck you are for your help! LOL!

[artik]

maybe b - a = 191 ? :scratch:

edit:

I got
a = 148
b = 339
c = 37
:dancin:

[LindaC781]

Sorry Artik....the first one, A = 131...

[artik]

Sorry Artik....the first one, A = 131...
Ohh :scratch::D


if A = 131, then this equation 10a + 20b + 30c = 9370 doesn't work :scratch:

[LindaC781]

I know...I got lost on that point too Artik!!

But all is not lost!! I got almost a 90 on the test for this chapter!! WOO HOO! Thanks for your help, all of you guys!!

Okay, next time it'll be about baseball or soccer, ok? :lol:

[artik]

I think some VIP tickets were for free :D

But all is not lost!! I got almost a 90 on the test for this chapter!! WOO HOO!
Congratulations!

[LindaC781]

I withdrew from the class. It was just too much for me. The pace was just too fast, and I didn't care for the online aspect of the course. Plus, I did very badly on my midterm...so I'm out right now. I will probably take the lecture version of this in the fall....I need the rest of the summer to recuperate from this experience!

[LindaC781]

I haven't given up. I start my new lecture-based class next week!! Wish me luck!

[LindaC781]

Got a 93 on my 3rd Intermediate (college) algebra exam!! That makes it an 83, 100 and 93 so far for marks!! WOO HOO!!

[BillieJean84]

OMG Thank you!! I'm in Math I started 2 days ago.... I hate it. Thanks again and godbless

Just to keep you all updated - I got an A for a final grade in my new College Algebra class!! Woo hoo!! I guess I did need to take the lecture class after all...

[BillieJean84]

I find out what I got in my college Algebra class today. I hope its at least a C / C+

[karom]

:puke: :puke: :puke: that explains everything :D

[BillieJean84]

:puke: :puke: :puke: that explains everything :D

you talkin to me? explains what?? lol. Maths my worst subject.

[karom]

^^lol can't say I'm bad at math but I most certainly hate it :puke:

[BillieJean84]

why for the love of god do we need math anyway???

[LindaC781]

I find out what I got in my college Algebra class today. I hope its at least a C / C+

Keeping my fingers crossed for you BillieJean84!! Good luck!

[BillieJean84]

Keeping my fingers crossed for you BillieJean84!! Good luck!


Thank yhou so much becuase if I don't get a certain good enough grade, I won't get any grants ; my financial aid will be changed....

[karom]

why for the love of god do we need math anyway???

I wonder the same thing :D

[kopwatcher]

I wonder the same thing :D

Without it, the interwebs wouldn't be possible :)

[Severus Snape]

I would have a much higher GPA if math did not exist. Well, actually, now that I think about it...I would have NO GPA if math didn't exist. :lol:

...I think I prefer it that way.

[BillieJean84]

I got a C+ in math part 1 !! But it brought my GPA down some. I start math 2 Jan.4

[BillieJean84]

Ok this question for review is the square root of 45 and the instructions are to rewrite it in simplified radical form.

Please help!!!

[This Is It!]

Never done this before, but I hope this is correct! ( \/ = square root ) …

\/45 = \/(9 * 5).

Since \/9 = 3, solution is 3\/(5) or 3 times square root of 5.

[BillieJean84]

ok what if its something like this square root (theres no sq.rt sign) of 28 and it says to write in simplified radical form...

and this problem -((-1) ^ 2 -3) ^2 + 5*3

[This Is It!]

Hope this is correct again! ...

\/(28) = \/(4 * 7).

Since \/(4) = 2, solution is 2\/(7) or 2 times square root of 7.

[LindaC781]

This is serious. If anyone needs any extra help in algebra, on a pre-calculus level, you can email me. I will try to help you....just PM me and we'll talk ok?

And when you do email me, type it exactly like it appears in the book your using...it's hard to see superscripts here...maybe even scan it in so I can see what you are talking about. I am a very visual person...I need to see it exactly like it appears in the book...

[LindaC781]

Hope this is correct again! ...

\/(28) = \/(4 * 7).

Since \/(4) = 2, solution is 2\/(7) or 2 times square root of 7.

Yes this is right. You need to break down the equation first into simpler forms, then solve.

[LindaC781]

ok what if its something like this square root (theres no sq.rt sign) of 28 and it says to write in simplified radical form...

and this problem -((-1) ^ 2 -3) ^2 + 5*3

Okay. Does it look like this?? <!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:PunctuationKerning/> <w:ValidateAgainstSchemas/> <w:SaveIfXMLInvalid>false</w:SaveIfXMLInvalid> <w:IgnoreMixedContent>false</w:IgnoreMixedContent> <w:AlwaysShowPlaceholderText>false</w:AlwaysShowPlaceholderText> <w:Compatibility> <w:BreakWrappedTables/> <w:SnapToGridInCell/> <w:WrapTextWithPunct/> <w:UseAsianBreakRules/> <w:DontGrowAutofit/> </w:Compatibility> <w:BrowserLevel>MicrosoftInternetExplorer4</w:BrowserLevel> </w:WordDocument> </xml><![endif]--><!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false" LatentStyleCount="156"> </w:LatentStyles> </xml><![endif]--><!--[if gte mso 10]> <style> /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} </style> <![endif]--> -((-1)^-2)*3)²+5*3?

If so, do the first parts first. -(-1)-2 is equal to -(-1/2) due to the negative sign on the superscript. Next, -1/2 * 3 equals -3/2. -( -3/2 ^2) equals -3^2/2^2 or -9/4. Next, 5*3 equals 15. Now put it all together, and you have -9/4 + 15 or -2.25 + 15. That turns out to be 12.75

I think you are having trouble with exponents...here's a good link for you...http://www.purplemath.com/modules/exponent.htm

[BillieJean84]

thanks much appreciated. Okay so I see what you did- you just simply broke it up.
The 4 exponent, is to the 3 in ( ) , then the 8 is to the y in ( ) then just simply do it...

thanks!!
