A little maths help...

[deadmanrising 715]

Before i begin support ends for windows xp today :D I hate windwos 7 and 8 but i have to buy it tommorow -_-

 

But anyways Ok so this is the question if someone can verify it for me.

 

X is 50% more than value of t

y is 10% less than value of w

 

Furthermore x=y

 

T/W as a decimal=________

 

So i thought that,,, x and y are integers so you cant actually reverse any fomulas to work out a fomula...

 

X=(T X 0.5) + T (since x is 50% more than t)

And

Y=(W X 0.1) - W (since y is 10% less than value of w)

 Since they are equal to each other

(T X 0.5) + T = (W X 0.1) - W simplified to 1/2T+T=0.1W - W Now i thought i could enter any single number into the foumla since x is y and y is x...

 So basically i just chose any random number (2....)

1.8/3 i got so as a decimal my answer was 0.6

For any other value should i get the same value? Can someone tell me if im right :) thanks

Don't you learn this in school?

IDK why your saying this, you don't know how to do this yourself.

If you have learnt it, why don't you help him?

Yea it's sad.

your question makes no sense. especially since your variables are set up wrong

[deadmanrising 715]

your question makes no sense. especially since your variables are set up wrong

This is the way the question was asked -_-

T/W=15/9=5/3=1.6 repeating

 

PS i used 10

if i use 2:

T/W=3/1.8= 1.6 repeating

 

the answer is 1.6 repeating

 

welcome

if makes total sense, you just must suck at math  <_<  -_-

lol,finding that kind of limit is practically impossible

[canadarules 1,938]

cough 97% in math cough not done any homework cough

make up a proper equation cough

[liam2rules 62]

it IS a proper equation

[canadarules 1,938]

nope also where is the question for this? you can't just write numbers with out a starting base....

[liam2rules 62]

the equations are

 

(x*1.5)/(y*.9)

x=y

x and y= any real numbers

 

its quite simple

my answer was 0.6

Can someone tell me if im right :) thanks

Yep, that's correct, you get 90% of your number over 150% of your number, which always cancels to 9/15 which cancels to 3/5 which = 0.6 as a decimal

[liam2rules 62]

oh whoops i switched the variables thanks!

[liam2rules 62]

but the point is canda is wrong  :P  <_<  -_-

[liam2rules 62]

oh whoops i switched the variables thanks!

wait but it is T/W so it would be 1.6 repeating... it would be six the other way but it is T/W

and im only 12 so i might make some mistakes bear with me here

[Lhamster 4,081]

Read it carefully, T is smaller than x or y, W is bigger than x or y. So T/W is smaller than 1.

Oh I get it I read it wrong so it is .6. Thanks for your help and wait til my mom hears that tanki is a math friendly site!!

1+1=1

You don't believe me?

4-4=4-4

2*2-2*2=2(2-2)

The left one is difference of squares, so:

(2+2)(2-2)=2(2-2) /:(2-2)

2+2=2 /:2

1+1=1

[sKy167 10]

:huh:

[Lhamster 4,081]

(2+2)(2-2)=2(2-2) /:(2-2)

And this is where this fails as 2-2 is 0, and you can't divide by 0.

[red_tank_the_best 300]

And this is where this fails as 2-2 is 0, and you can't divide by 0.

That's correct! Actualy, nobody who I show this find the mistake which makes this the prove why 0 can't divide anything :P

That's a real maths problem, but I have another one waiting to be posted...
