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!
 
That's a dirrrrrttttyyyyy word in my eyes!! I avoid algebra like the plague! xP
Yet, somehow, I passed it. Go figure lol.
 
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.
 
On behalf of all Arabs in this world, I sincerely apologize for bringing this horrible, HORRIBLE subject to existence! Please forgive us!!! :doh:
 
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.
 
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.

I am personally buying you a six-pack, whoever can help me out with this first!! No kidding!!!
 
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!
 
maybe b - a = 191 ? :scratch:

edit:

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

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!
 
Got a 93 on my 3rd Intermediate (college) algebra exam!! That makes it an 83, 100 and 93 so far for marks!! WOO HOO!!
 
OMG Thank you!! I'm in Math I started 2 days ago.... I hate it. Thanks again and godbless


WORD PROBLEMS if someone can help me please....
