Your answer is correct Solveit.

Haylyey found    

  p when d=10 insteads of finding

What is the value of d when p =10     :)

Hi Solveit,

I have checked the first 2 and I have commented on the last one.

I have not looked at the others yet :)

Thanks guest :)        Yes, this is an interesting question Solveit,          

I have put this aside for the next wrap so others can look at it too :)

5+2x-3x^2     DOES have two variable terms in it.

Good day to you all,

We have had some terrific answers this Sat/Sun delivered by CPhill, Alan, Geno3141. Solveit, Dragonlance, Dragonslayer554, asinus, rarinstraw1195 and Anonymous4338.    Thank you   

Camelot News:

For a while now, Mistress Coldplay has been Camelot's Royal Historian.  She is studying her doctrate!  Soon she may be Doctor Cold, but she will not get too big a head,  she will still be 'Play'ing about in all our historical records.

Anyway, she has nominated a whole heap of old historical threads.  I asked her to nominate just one but maybe she did not understand me properly or maybe she just got caught up in all the excitement. Anyway, here is her post of threads that she nominated for tonight. 

1) History (and comedy) posts provided by Camelot's very own Royal Historian.  I Thank yea Mistress Coldplay   

Nice answer Solveit!

CPhill has nominated your answer here for the wrap.

That is a BIG compliment.        

Congratulations :)

Thanks Chris    

lga+lg1/a=0 

Is this true or false? 

I think it is true only if a=1.

\(log\;a+log\frac{1}{a}=log\;(a*\frac{1}{a})=log\;1 = 0\)

So true  :)

lga+lg1/a=0 

Is this true or false? 

I think it is true only if a=1.

Is this equation a quadratic one with two variable terms?

5+2x-3x^2 I think it is quadratic but it doesnt have two variable terms in it so it must be false?

What could what be?  The question does not make sense ://

Thanks Chris,

It is not often that we can show up these fancy calculators - and it is not just the web2 calc either  it is almost all calcs that you can find :))

[1/6 - 1/3] / 1/7=

[1 - 2] / 6=

-1/6 / 1/7=

-1/6 X 7 =

-7/6=-1 1/6

I'm assuming that the numbers are supposed to be "60%"   and "12"   ....if so

12  = 60%   of the total items to be purchased.......so....using a proportion, we have

12/60  = N / 100   where N  is the total items  on the list

1/5 = N / 100      cross-multiply

100/5  = N   =   20   items to be purchased
