I am trying to help my DH with his Algebra homework and I am so stuck right now on 3 problems. I bet I know how to do them just need a memory jolt!
Can anyone help me??
I will try my best to write them out but it's hard to type out an equation. :nutts
1) 3x+2
------ (division bar lol)
2


2) 6
-----
x+3



3) 16 with the faction 3/2 written as an exponent. I have never seen anything like that before.. I haven't made it past intermediate alg in college yet though...


I soooo appreciate anyones help! Thanks! :hugs

UGH I hate math!sorry sweety

OMG ME TOO :gaah
I hate doing my own algebra but he failed this already so I am trying so hard to help him since he works like 60+ hrs a week (afternoon/nights) I feel bad for him :sigh but Im in remidial math so I can help him with some of it but some is out of my league so I have to self teach myself to teach him :lol He is in an accelerated program so its jampacked for 5 weeks and thats it.

What are the first 2 asking for. You can't solve for x

For help with number 3 google "fractional exponents"

number 1) The two's, divide by both of them to get 1. So it's 3x+1=Blah

2) split it up...6/x + 6/3.....so then it's (6/x) + 2 = blah. Minus the two from both sides and multiply the answer by 1/6 and you get X :)

3) 16 with the faction 3/2 written as an exponent. I have never seen anything like that before.. I haven't made it past intermediate alg in college yet though...

so is it 16 raised to the 3/2?

If that's all it is then you just multiply 16 x 3 and divide by two.

Or just raise 16 to the 1.5th power. I think...

The assingment has problems worked out on them and you have to figure out if they are correct and if incorrect fix them... that is all it says is 3x+2 divided by 2 :dunno
They solve them so crazy. It has 3x+2/2 then beside that it says 3x+1/1 = 3x+1 but I don't get how they did that or if its correct

Gillian, on #1 that's how they did it, but how can you divide the expression 3x+2 by the bottom 2? wouldn't you have to divide the 2 by the 3x as well? Why just the 2? Sorry Im sooo lost :lol I get the fraction exponent now thanks :)

Gillian, can you write out #2 for me?? I am lost after splitting them up.

lol...well, seeing as how you have both integers 2 and 2, they divide by itself. :) So it's just one.

You could do it the same way and 3/2x = blah-2 and then multiply the answer by 2/3

number 1) The two's, divide by both of them to get 1. So it's 3x+1=Blah

2) split it up...6/x + 6/3.....so then it's (6/x) + 2 = blah. Minus the two from both sides and multiply the answer by 1/6 and you get X :)

Your advice for 2 is def wrong. "Splitting up" the denominator defies the laws of mathematics.
Proof: plug in a number for x and solve the original eq then what yo plit it up to. Not equal, not right.

need to do this equation on paper!

oh shoot...I forgot you can only divide up the numerator.

RC...couldn't you multiply 6 by X+3/1?

I sure can!

6/x + 6/3 = answer

(6/x) + 2 = answer

(6/x)= answer -2

(1/6) x (6/1x) = answer -2 (1/6)

x = answer -2 (1/6)

is that better Cori?

This is not right.

6/x + 6/3 =/= 6/x+3

The problem cannot be simplified further. Neither can #1, so the solutions showed on cori's dh's paper are invalid. Check order of ops concerning fractions.

Only if the equation were set equal to something so you could do it on both sides. Doing what you say here would change a division prob to a multiplication prob.

Crap. You are right on #1 regarding the num. I took algebra in 8th grade. That was a long ass time ago.

Maybe this will help you see what I see :lol

I am sooooo confused :nutts
They solved problems and you determine if they are right or wrong if wrong you correct them...
The ones in question are #9 and #12

Oh you know, I just realized in the instructions it says to state if its correct and if incorrect fix it or explain why some can't be simplified. So, those 2 may be simplified all they can right? I couldn't see how to simplify either of them

My DH's professor just emailed me back and said that you can split a numerator and reduce separately but not a denominator. So does that mean that 3x+2/2 you can cancel the 2s and it leaves 3x+1 as the answer?
Im sorry for so many stupid questions... Its hard doing online math through DH's school... Mine is completely different but Im going to be going to a local community college online so I have to have actual exams proctored and such, DH doesn't have exams.

Yes! You can split the numerator up :)

It would be 3/2x + 1 :D

referring to the pdf, #9 is correct, #12 is incorrect.

this link will show you how to do the fractional exponent

Thanks Hun that helped alot! :)
