Any Math Whizzes out there??? - GoFuckYourself.com

Having a little trouble with this one. Any help would be greatly appreciated.

If 15 times the reciprocal of a number is A=added to the ratio of 9 times a number minus 7 and the number is plus 2, the result is 9. What is the number?

Can you set this one up? I bow down if you can.

Thanks,

I wish I cold be more clear. However, This college instructor unfortunately needs a "plexotomy."

Plexotomy: Surgical proceedure where a doctor cuts a square out of your abdomen and places a piece of plexiglas over the hole so that you can see where your going when you have your head up your ass.

Can you maybe try and decipher what she is trying to say???

Thanks,

15/A + (9A - 7)/(A+2) = 9

Think that's it if I read right.

Not a whiz tho, just a programmer.

15/A is inverse of the number
reciprocal is A(-1) I believe

wtf is a reciprocal of a number?

i took lots of math in college, never heard of the term

jennym · 11-30-2003, 09:55 PM

The recip of a number means when they are multiplied, the answer is 1.

Ex. 3 x 1/3 =1

Those numbers are recips

MetaformX · 11-30-2003, 09:56 PM

go with the sum of zero. thats the answer to almost everything

exactly

X hahahaha> 1/X is inverse
X hahahaha> -X is opposite
X hahahaha> X(-1) is reciprocal

You're only considering scalars. When dealing with,say tensors , the difference becomes more important .
