|
B = A - (C/100) |
||||||||
|
|
|||||||||
| |||||||||
|
|
erm, no |
||||||||
|
|
|||||||||
| |||||||||
|
|
I might be completly wrong. but I'm guessing: (a+c)x100 ------------ = B 2 |
||||||||
|
|
|||||||||
| |||||||||
|
|
well? what is it then? :) |
||||||||
|
|
|||||||||
| |||||||||
|
|
I don't know, and, after but a moment's reflection, I decided I didn't want to. |
||||||||
|
|
|||||||||

|
|
If you had the outcome then it'd be easier. |
||||||||
|
|
|||||||||
| |||||||||
|
|
[(A-B)/B] * 100 = C (A-B) * 100B = BC A - B = BC/100B A - B = C/100 B = A - (C/100) |
||||||||
|
|
|||||||||
| |||||||||
|
|
dont you have to turn the first half into (A/B - B/B) x 100 ? |
||||||||
|
|
|||||||||
| |||||||||
|
|
Your maths is terrible. Please stop. |
||||||||
|
|
|||||||||
| |||||||||
|
|
well fine then, post a solution yourself |
||||||||
|
|
|||||||||
| |||||||||
|
|
I bet you need to use a reciprocal. God I love reciprocals. Someone use a reciprocal. |
||||||||
|
|
|||||||||
| |||||||||
|
|
(A-B)x100=BC A-B=BC/100 A=B+(BC/100)=B[(C/100) +1] A B= ___________ (C/100)+1 |
||||||||
|
|

| |||||||||
|
|
Err.. Hmm.. Uhm... Bhm.. Word to xceque! |
||||||||
|
|
|||||||||
| |||||||||
|
|
I have to say I think you are wrong redrum, but thanks for the best effort yet |
||||||||
|
|
|||||||||
| |||||||||
|
|
ok so everyone is gonna post something and we'll never know the right solution. |
||||||||
|
|
|||||||||
| |||||||||
|
|
Easy |

|
hell yeah my n**** dozer done did it!!!! |
||||||||
|
|
|||||||||
| |||||||||
|
|
not unless aphextriplet pipes up with some genius |
||||||||
|
|
|||||||||
| |||||||||
|
|
[ (A-B)/B ] x 100 = C [ A/B - B/B ] x 100 = C [ A/B - 1 ] x 100 = C (100A)/B - 100 = C (100A)/B = C + 100 100A = (C + 100) x B (100A) / (C + 100) = B |
||||||||
|
|
|||||||||
| |||||||||
|
|
i think dozer has made more progress. Even though his post messed up at the end. |
||||||||
|
|
|||||||||
| |||||||||
|
|
[ (A-B)/B ] x 100 = C [ A/B - B/B ] x 100 = C [ A/B - 1 ] x 100 = C (100A)/B - 100 = C (100A)/B = C + 100 100A = (C + 100) x B (100A) / (C + 100) = B goddamn you people, lazy lazy. |
||||||||
|
|
|||||||||
| |||||||||
|
|
This was the good result actually |
||||||||
|
|
|||||||||
| |||||||||
|
|

||||||||
|
|
|||||||||
| |||||||||

|
|||||||||
| |||||||||
|
|

||||||||
|
|
|||||||||
| |||||||||
|
|
Meh. I was employed as an I.C.T teacher. I just teach maths because i have a degree in it. |
||||||||
|
|
|||||||||
| |||||||||
|
|
wait a minute hedphukker (100A) / (C + 100) = B Dozier A / (C/100 + 1) = B who is right? |
||||||||
|
|
|||||||||
| |||||||||
|
|
i got um (100a/c)+a=b |
||||||||
|
|
|||||||||
| |||||||||
|
|
It's the same!!!!! |
||||||||
|
|
|||||||||
| |||||||||
|
|
OMG! Don't ever talk with me! LOL |
||||||||
|
|
|||||||||
| |||||||||
|
|
and i got it 2 different ways |
||||||||
|
|
|||||||||
| |||||||||
|
|
HOW ARE THESE POSSIBLES? |
||||||||
|
|
|||||||||
| |||||||||

|
LOL |
||||||||
|
|
|||||||||
| |||||||||
|
|
ok this is how I did it: A-B ---- x 100 =C B A+C ----- x 100 = B B A+C x 100 = B x B A+C x 100 = 2 x B A+C ----- x 100 = B 2 or is it [(A+C) x 100] -2 = B where have I gone wrong? |
||||||||
|
|
|||||||||
| |||||||||
|
|
this seems simple yet i wouldn't know how to solve it ... : | i've never been good at math, and it's been years since i last solved an equation. math is something so easily forgettable. (i wonder whether this topic would make a math teacher sad or make him laugh...) |
||||||||
|
|
|||||||||
| |||||||||
|
|
I found a mistake A-B ---- x 100 =C B A-C ----- x 100 = B B A-C x 100 = B x B A-C x 100 = 2 x B A-C ----- x 100 = B 2 or is it [(A-C) x 100] -2 = B |
||||||||
|
|

| |||||||||
|
|
It would make him act like an idiot, apparently. |
||||||||
|
|
