WHAT IS A TARDIS YOU ASK !

> is this an English site?

Mais oui!  :smile:

> why does everyone care what x is equal to?

Because, as you well know, X marks the spot! 

The median is the middle number so ...

Let the numbers be A, 7, B

(A+B+7)/3 = 5

A+B+7=15

A+B=8

now remember that A and B are whole positive numbers and    $$A\le7\le B$$

So the only possible numbers are    1,7,7

The range is 7-1=6

There is no biggest number  

A persons paycheck at the start of a new contract is 9000 a year, two years later his paycheck is 10, 112.4, how much percentage did his paycheck go up in. Please explain

$${\mathtt{10\,112.4}}{\mathtt{\,-\,}}{\mathtt{9\,000}} = {\frac{{\mathtt{5\,562}}}{{\mathtt{5}}}} = {\mathtt{1\,112.4}}$$

$${\frac{{\mathtt{1\,112.4}}}{{\mathtt{9\,000}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\frac{{\mathtt{309}}}{{\mathtt{25}}}} = {\mathtt{12.36}}$$

I am not sure if you have already asked this exact question today or if you have just asked several similar questions.  Either way it is time for you to learn from the other answers.

What do YOU think the answer might be ??

Yes anon I believe you are correct.    

It is a rare day that Heureka makes any error  - but it is very easily done   

Thanks Heureka,

Here is the graphical solution

Just type pemdas into google.    

Yes Zac, I am with you :)

CPhill, you made a boo boo

Can you do this one MG

How do you solve 2(x-3) + 5x = 4(x+2) - 5 ?

Zac's answer (Zac gives great answers))

just find the distance between the 2 points :)

Use distance formula

okay, I will go for blue :)

Hi ShadowBolt04,

I don't think so but it would not work very well anyway because they could be garbage answers.  

On the Questions Page, if  a question has been answered, a little dot appears in the middle bottom of the question.  2 dots means 2 answers etc.

If you press on the dot then a drop down will show you previews of the answers.

Perhaps you can make use of this feature
