Didn't I answer this one before for you Kool-aid?

We don't have Kool-aid in the shops in Australia.  I miss all the 'product' jokes around here.

Never mind, from what I gather is is a bit like codial, which I don't like anyway.

AND WE HAVE

TIM TAMS                               

You just don't know what you are missing out on!

That is great Kool-Aid.  

I would interprete this question a little differently.  What do others think?

I think it is

|-17- -8|

=|-17+8|

=|-9|

=+9 or just 9

Q:  Solve for LASER+REAL=SHARE, and replace each letter to a number?

2/3X +4/5 = -17/30

30 is the lowest common denominator so I would just multiply both sides by 30 right from the beginning.

$$\begin{array}{rll}
30\left(\frac{2x}{3}+\frac{4}{5}\right)&=&30\times\frac{-17}{30}\\\\
20x+24&=&-17\\\\
20x&=&-41\\\\
x&=&\frac{-41}{20}\\\\
x&=&-2.05
\end{array}$$

No Ninja that is not what I was saying at all.

Your (first) answer of 16 pieces was totally correct.

I DO NOT think that an answer of 16.4 repeater peices is any where near as good an answer as just 16pieces

---------------

Here is a different question so that you can see what I really meant.

How many 0.9 yard peices can be cut from a peice of cloth 6 and 8/10 yards long.

If I take your explanation literally then I can discard the 8/10 because I can't get a whole 0.9 yard out of it.

This will leave me with 6 divided by 0.9 = 6.6 repeater = 6 whole lengths

BUT

if you did not discard the 8/10 then you have 6.8/0.9= 7.5repeater = 7 whole lenths

SO you see in this second example you can see why you cannot discard the fractional or decimal bit until the very end.  Do you get what i am saying?

Thanks Chris,

Yes sorry Sally , I didn't check this.  But it shows you that getting the axis of symmetry straight from the quadratic formula is a really good thing to understand.
