Math question
 

-25/27x + 8/9 = 1/3

How do I determine what x is?

You express the entire fraction with a common denominator (27) and then you merge the 2 fractions on the left hand side to one, then cross multiply to isolate x and find the value.

Heres one for ya!

I had to take Algebra twice sorry no help here but my wife is a wiz let me get her.

PS: The answer is 5/3...
WG

taking couple of crown royal shots....and ill re read this thread and post the answer

How about 3/5

I am helping someone with something I was no good at 36 years ago

lol i WAS an algebra wiz.
but that was over 12 years ago now. :)

If the x is in the denominator, then its 5/3. If its the numerator, 3/5.
WG

Can you explain this one in long math? I know the answer, but I will be damned if I can discuss why.

Well, the online test is saying it is 3/5

You sure the x is in the denominator?

:1orglaugh

fucking nerds

-25/27x + 8/9 = 1/3 is what I was given

Is it

(-25/27) * x + 8/9 = 1/3

OR

[-25 / (27x)] + 8/9 = 1/3

?!?

Is the X in the numerator or denominator though? The way you wrote it puts it in the denominator.
WG

I believe the latter

Well, I have an "expert" here and he is coming up with 1 2/3 which is the same as your 5/3 . . . so maybe they are wrong

Its either this

or

depending on the position of 'x' .. whether it was with numerator or denominator.

The answer is either 5/3 or 3/5 depending on where x is. If its the numerator, then 3/5, if the denominator, its 5/3. Figure out where x is and you'll have the answer.

Err, one part was false.


If 'x' is denominator, its ..

So, WG is right and first to solve :thumbsup

I got 5/3 in two different ways:

27x(-25/27x) + 27x(8/9) = 27x(1/3)
-25 + 3x(8) = 9x
-25 +24x = 9x
-25 = -15x
-25/-15 = x
5/3 = x

-25/27x = 1/3 - 8/9
-25/27x = 3/9 - 8/9
-25/27x = -5/9
-25 = 27x(-5/9)
-25 = -135x/9
-225 = -135x
-225/-135 = x
5/3 = x

:thumbsup

-25/27x + 8/9 = 1/3


-25/27x + .888 - .888 = .333 -.888

-25/27x = .333 -.888

-25 / 27x = -.555

-25 / 27x * 27x = -.555 *27x

-25 = -.555 * 27x

-25 + .555 = 27x

-24.445 = 27x

-24.445 = 27x/27

-24.445/27 = x

-0.9 =x

oh snap you guys solved it

im really wrong?

shit

Okay, my brain just splattered across the room . . I need to go clean it up.

Thanks guys

Your error is here:

-25 / 27x * 27x = -.555 *27x

-25 = -.555 * 27x

-25 + .555 = 27x

You didn't calculate the product of -.555 and 27x when you multiplied both sides by 27x.

That would have been -25 = -14.985x.

You would have ended up with @5/3. By rounding the numbers you were off by .015.

whats the detonator?

You people have too much fucking time on your hands to be fucking around with that bullshit!

There are more important things that need to be done. :2 cents:

you guys are pathetic, this is 3rd grade math for fucks sake... a retarded 10 year old kid could solve this with his eyes closed...

is it -25/27x or (-25/27)x?

:1orglaugh:1orglaugh

Well, as it was described to me orally (I did not get to see the question) I have come to the conclusion it is the latter.

uh huh huh huh huh, he said "orally" :1orglaugh

I 2nd that, although I'd say it would need a 12-13 year old non-retarded child IMHO.

It is 8th grade math, and it has been a VERY long time since I was in the 8th grade.

LOL, it was just a simply equation for kids. Why do you think someone need "too much fucking time" to calculate it? Less than 2 minutes is not too much time I believe :2 cents:

-25/27x + 8/9 = 1/3

is a same as

(-25/27) * x + 8/9 = 1/3

and it is a same as

-25x / 27x + 8/9 = 1/3

and of course it's not [-25 / (27x)] + 8/9 = 1/3 :winkwink:

P.S. The elementary school rules :winkwink:
