In a 1/N fraction, if we cannot write the denominator in terms of factors of 2's and/or 5's, then the decimal repeats......and the maximum length of its repeating string of digits is never greater than N - 1 digits

(x^2 - 1 ) / (x-1)      factor the numerator

(x + 1) (x - 1) / (x - 1)      "cancel" the (x - 1) terms

= ( x + 1 )

The "2m" is correct

What is -10 + 6   ???

Okay so is it 2m + 16?

Let's look at this again

9q+24=3(3q-4)    so we have

9q+24= 9q - 12    

Note that this doesn't have a solution...to see why, note that if I add 24 to 9q  ...  it can't possibly be equal to the same thing as subtracting 12 from it.....!!!!

These are not the same.

A cylinder is a prism and the volume of any prism is the area of the cross section times by the height (or depth as I often prefer to call it)

The cross section of a cylinder is a circle and its area is   $$A=\pi r^2$$

So  the volume of the prism is     $$V=\pi r^2h\quad units ^3$$

Now I could probably only give a calculus reason as to why the SA of a sphere is   $$SA=4\pi r^2\quad unit^2$$

But anyway they are  not the same.

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

I know you gave a calculus answer for another question.  Did you actually understand it or did you copy it.

I don't mind either way - it was a great answer.  I am just trying to assess your level.

2(m-5) + 6     distribute the 2 over the terms in parentheses

2m - 10 + 6    can you finish it??? (just combine like terms)

Yay I got it right thanks for helping me make sure!

q= -36 because 9q and 9q eliminate themselves so you are left with q. Then subtract 24 from both sides to get q= -36.

She's already spent $10

So...she has $60 left....and she can't spend more than that

So we have

$10 * L ≤ $60    divide by $10 on each side

L ≤ 6      where L is the number of lipstick kits

Here's an easy way to solve this kind of problem....

Divide 84 by 3  = 28

So.....28 + 28 + 28  = 84

Subtract 1 from the the first 28 and add 1 to the last.......so....

27  + 28 + 29= 84      .....just as you found.....!!!!

It would change the unit rate per each item because your saving money from the coupon so it changes the price! At least I think that is why it would change idk I would double check with someone else!

Have them take a shower after their done the shower do NOT have them brush their hair that way the hairs are separated! 

Are you asking what a percentage is?

Welcome to the forum fiflvm97.  I hope that ou like it here.      I can see that you will be a great asset to us if you choose to stay around :)

I have been looking at these answers.

Geno, yours is concise but exactly what the asker would have wanted.    

flflvm,  I loved your analysis of this answer.  Adding the diagram made all the difference too.

I hope that some of our senior students really think about what you said - as I did.  It would be of great benefit to them.  

Chris,  I had not thought before about the volume of a cone being one third of a hemisphere.  It's an obvious conclusion now that you point it out.

As for the rest of what archimedes said that will require a more concentrated effort from me.  Thank you for discussing it.   

The diagonal is given by (√2)*5.25 in  = about 7.4 in.

Note that the first term is 1^2

The second term is 2^2

So....the Nth term  is just  N^2

Use the tangent inverse, i.e.

tan^-1(1/3) = θ = about 18.4 degrees  (or about 198.4) degrees

W/4 - 4 =3    add 4 to both sides

W/4  = 7       multiply both sides by 4

W = 28

that is true

First, you have to imagine a 1 in front of the x. Then, you subtract 1x on both sides and you will get 10=9x. Next, you will have to divide 9 on both sides and you will get 10/9 ( as a fraction) 1.1111111111 ( as a decimal)
