@taffytracer. Its not to be funny, its just something from vine.

 i need to know the value of x  

  1 2/3*3

you take the fraction, and turn it into an improper fraction: 5/3

then you just multiply across

=5/3*3/1

(5*3)+(3*1)

=15/3

Simplify

=5

I am afraid I cannot answer that question. It is my Mom's personal information.

a variable

Well, 9+10=19

But some people to be funny and cool say 9+10=21. XD

The method is to look at the final digit, it has to be a 1 or a 9. (Choose an intermediate digit like 5 for example  and some of those to the left will be bigger, and some smaller.)   Similarly there will be two choices for the digit in the eighth position, two choices for the digit in the seventh position and so on.  There will only one choice left for the first digit, so 2 to the eight or 256 possibles

n+n+3+2(n+3)

Well, you should always add like terms.

n+n=2n

Then you should use distributive property

2(n+3)

(2*n)+(2*3)

2n+6

2n+2n+3+6

Add like terms

2n+2n=4n, and 3+6=9

4n+9 is your answer.

I have no idea

The answer is 19

$$12*2^{-2}=12*\frac{1}{2^{+2}}=12*\frac{1}{4}=3$$

If we made each piece 4 feet long, there would be 3 feet of ribbon left over. 3 feet equals 36 inches, so if we divided this among the 18 pieces we could give each 2 more inches, and there would be no ribbon remaining.  So the answer is each piece could be made 4' 2" exactly.

because pi actually is irrational and has an infinite amount of digits (or so we think) so we shorten it to the first three because usually you dont have to get too specific with circles. but when you do, um, itll be like actual pi or whatever

$${\mathtt{\pi}} = {\mathtt{3.141\: \!592\: \!653\: \!589\: \!793\: \!2}}$$

except it doesnt just end there it keeps going

(1 + 2/3) * 3
=3+ (2*3)/3
=3+ 6/3
=3+2/1
=3+2
=5

P- ( ) do whatever is in the prethesis first 

E- ^ then any exponets

M-x multiply

D- / divide

A-+ add

S- -subtract

Well, XY is 10 you are right about that.   

So long as the method is correct I am not too concerned.

I am sure you can fix the careless errors I thought there was likely to be some. 

I take it you were happy with the method ?

There is probably a much easier way,  I have a reputation for taking the scenic route.  :))

$${\sqrt[{{\mathtt{{\mathtt{4}}}}}]{{\mathtt{10\,000}}}} = {\mathtt{10}}$$

its ten

you can plug in different numbered roots in by typing sqrt(x, y) where x is the radicand or whatever you call the thingy under the radical sign and y is the root number thing.

like this: $${\sqrt[{{\mathtt{{\mathtt{y}}}}}]{{\mathtt{x}}}}$$ thats by typing sqrt(x, y) just plug in your own values

21?                 

diameter times pi but next time just check the formulary up at the top

why would you do this

(2,2)   (-2,5)

First, subtract the x coordinates....order doesn't matter...so we have

-2-2  = -4

Square this   (-4) ^2   = 16

Now do the same proceedure with the y coordinates...again, order doesn't matter

5-2 = 3

3^2  = 9

Add the 16 and the 9  = 25

Now....take the square root of this

√25  = 5    ....and that's the distance between the points......!!!
