Ok, serious question...can anyone help me with College Algebra????? I am going to school online and my instructors arent any help when it comes to this. I have failed College Algebra once. I have to pass with at least a C to get my degree. Can anyone help me????

This is one of my problems,
1/4X+3/2X=7

HUH????

Sorry, I was just told a few weeks ago that I'll have to take a remedial Pre-Algebra class before I can get my degree as well. I took Algebra II in HS, but I'm so rusty (read OLD) that I can't remember it. English, I clep'ed out of both, Math and Science - NO THANKS!

1/4x+6/4x = 7

7/4x = 7

7/4 = 7x

1/4 = x

Show off.

Hey, WOW for the first time EVER that made sence. Can you help me please Thor???

Oh and Thank you sooooo much

I didn't explain my solution the first time so here goes

1/4x+3/2x=7

find common denominator (4x), so

3/2x = 6/4x

which makes

1/4x+6/4x = 7

Add fractions

7/4x = 7

muliply both sides by x

7/4 = 7x

divide both side by 7

1/4 = x

Here is another approach

multiply both sides by x since (1/4x + 3/2x) = 1/x(1/4+3/2)

x(1/4x+3/2x) = 7x = 1/4 + 3/2 = 7x

common denominator

1/4 + 6/4 = 7x

add fractions

7/4 = 7x

divide by 7 to simplify

1/4 = x

I have to do this stuff all the time with my 15 year old, she can whip out a english paper in minuets, but for some reason she can't remember the math end of it even though I have explained it hundreds of times and she gets it when I do. Only thing is I get rusty because its been a while sense college and I have to reteach/refresh myself because I simple don't use algebra at work. Ugh, when and if she goes into calculus I will have to reteach myself that also, those days will be interesting if I don't have a nervious break down first.

My first job out of college I was working with mathematical modeling. It was kind of cool that I got to use calculus on the job after all those years of studying.

my calculus is quite rusty now. I think I could still figure out the derivatives of cosine and sine.

Its when they got off integrating log funtions that I scratched my head a bit, lets not mention ODE and linear algebra , but I made it through, sadly if I wanted to go back and finish my engineering degree I would probly have to take a lot of the math over just to cover what I forgot.

Wow- Im lost!! I am horrible at math- and its funny, cause I now work in an accounting related field with numbers all day!! HAHA

Oh, and its been proven that generally speaking, women tend to excel at English and History, men tend to excel at Math and Science.

I just got the "NE1" part of the title of this post. It took me a while.

Anyone?

Wow...okay when I need help I'll be posting! I'm pretty good at Algebra and Math and Science...but it'll be the english stuff I'll need my help with.

SFV is soooooo cool.
