sorry generic but as a kid who goes to school everyday and is constantly lectured on putting commas here and periods their! I would sometimes like to get on the internet and not be judged, but who am i kidding its the internet haha! If it makes you feel any better i have a 96 A in english so their.

Z-man, just a friendly question. Do you have an artofproblemsolving account? I feel like I have heard of that name before. This is Mellie. I was too lazy to login haha.

1 meter   = 39.37 in

So......

39.37 / 12  = about 3.28 ft.

Let's  walk this through step-by-step

[ 2x - 4] / 3   + 2   = 1/2      multiply through by the common denominator of 2 and 3   = 6

2 [2x - 4] + 12  = 3              subtract 12 from both sides

2 [2x - 4 ]  = - 9    simplify

4x - 8   = -9          add 8 to both sides

4x   = -1               divide 4  by both sides

x  =  -1/4

Multiply the exponent of x by 2giving

The answer is

x^2 evaluates to 

Multiply x and 9

Multiply x and 1

The x just gets copied along.

The answer is x

x

9*x evaluates to 9x

x^2-9*x evaluates to 

The answer is

x^2-9*x+14 evaluates to 

To divide by x

divide each term in by x term by term.

To divide by x

Divide by x by subtracting the exponents, and keeping the x, to get x

The answer is x

 ÷ x = x

To divide x by x

Divide x by x by subtracting the exponents, and keeping the x, to get 1

Why 1? since subtracting the exponents gives zero, the x completely drops out.This because anything (other than 0) to the 0th power is 1.

-9x ÷ x = -9

To divide 1 by x

The x just gets copied along in the denominator.

The answer is

14 ÷ x =

(x^2-9*x+14)/x evaluates to 

-9 - 7 = -16

The answer is

(x^2-9*x+14)/x-7 evaluates to 

Plz delete this post/thread.

Sadly, you were wrong. I banish thee forever for using an online calculator. I will never trust you or your answers ever again.

Thanks!!!!

Multiply the exponent of n by 2giving

The answer is

n^2 evaluates to 

Multiply n and 3

Multiply n and 1

The n just gets copied along.

The answer is n

n

3*n evaluates to 3n

To divide n by 1

The n just gets copied along in the numerator.

The answer is n

3*n/3 evaluates to n

Multiply and n

Multiply the and n

Multiply and n

Combine the and n by adding the exponents, and keeping the n, to get

The answer is

3*n/3*n^2 evaluates to 

What is the question  ???

There are 12 total counters. You get 12 by doing 5+6+1. Take the amount of red counters and subtract it from the total number of counters by doing 12-5. Your answer is 7. Put that over the total, and the probability of Jim not picking a red counter is 7/12.

Hope this helps 

Ther are 12 counters....7 are not red....so....the probability that a red one is not selected = 7/12

Well thought out answer, Z-Man......the admin may be working on obtaining an app that screens out some of this inappropriate garbage....you're right, of course......there are always going to be idiots......you can't screen all of them out.....!!!!

@zegroes As a grammar n**i, it literally gave me a migraine reading your post. No commas, overly long sentences, etc...    It breaks my heart.

for one you lost me at delete the forum entirely lol talk about saying s***w it and throwing all the history down the toilet. And no i think making it members only would be a bad idea too because just think about it. People are lazy. Make people sign up and they will stop coming make people stop coming and this forum will DIE! I get what your problem is and seriously once you think about it. It cannot be solved. Their are always going to be people who troll i mean we are online so yeah....Nothing you can really do.

We have  .....

tan 30  = 12,400 / d    where d is the distance we're looking for....rearrange....

d = 12,400 / tan 30   ≈ 21477.43  ft.

$${\frac{\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{4}}\right)}{{\mathtt{3}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}} = {\frac{{\mathtt{1}}}{{\mathtt{2}}}} \Rightarrow {\mathtt{x}} = {\mathtt{\,-\,}}{\frac{{\mathtt{1}}}{{\mathtt{4}}}} \Rightarrow {\mathtt{x}} = -{\mathtt{0.25}}$$
