88.8650663 is your answer mr anonymous

You can't unless it algebra aha x

i think its the diameter

not that this answers your qustion, but that translates as I like to give me the result in degrees, minutes and seconds ??

@beary i think anonymous is being specific enough.

@anonymous, you type a minus symbol in front of the number so negative 53 would be -53.

If your team scores 4 runs in the first three innings, then, at that rate, it will score another 4 runs in the next three innings and another 4 runs in the last three innings:  4 + 4 + 4  = 12 runs scored.

Pasting that into the calculator at this site, I got the answer of 68140.

Use the method of "linear combinations":

-4x - 15y  =  17

 4x - 20y  =  52

Add down the columns to get:

      -35y = 69

          y  =  69/-35

Substitute this value back into either one of the original equations; I'll use the second one:

  4x - 20(69/-35)  =  52

                    4x  =  88/7

                      x  =  22/7

muchas gracias!

Hi anon :)

Hi all,

Our much valued answerers today were Tetration, Happy7, fzoqu, Geno3141, Rosala, ThisGuy, Mathematician, GenericUserName, Alan, Heureka and InnovativeProgrammer.  Thank you all. 

Interest Posts:

You need to be more specific

Fri 20/2/15

Three thousand one hundred and forty five Times nine hundred and forty five minus eleven

3145 x 945 - 11

enetr this in a calc and you'll get the answer!

Thanks Heureka,

It took me a while to work out what you were doing and it will take me much longer to work out why it works but that is really nifty.

Thank you for showing me.

On this calc you use

acos(0.68)

Hi Rosala, the question is ambiguous BUT

$${\frac{{\mathtt{250}}}{{\mathtt{56}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\frac{{\mathtt{3\,125}}}{{\mathtt{7}}}} = {\mathtt{446.428\: \!571\: \!428\: \!571\: \!428\: \!6}}$$

Your answer belongs to a different interpretation

$${\frac{{\mathtt{56}}}{{\mathtt{250}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\frac{{\mathtt{112}}}{{\mathtt{5}}}} = {\mathtt{22.4}}$$

Thanks Alan.  I hope it helps a bit anyway. 

Did you wach that clip of the magnetic levitation train in Shanghai?  The most amazing bit is when the two trains - each with many carriages pass.  The passengers don't even 'see' the other train.  It really is amazing!

You know, we use pictures and graphs to help illustrate things all he time but making sense of these 'aids'   is a learned skill.

For anyone who is reading this I greatly encourage you to try and figure out the relevances of the pictorials that we show you.  If you learn to interprete graphs etc properly it will help you enormously.

Never be afraid to ask questions.  We actually enjoy being cross examinied.  It is the only way that we really know we are teaching/helping people.

Thanks for fixing it Rosala :))
