The same answer to how many 3 digit numbers consist of only odd digits.

Are those two equations?
If so
1. get the recipical of either fraction (flip)
act as though it is now multiplication (multiply numerators and denominators)
and
2. 8 is 8/1 so multiply that with...

If you know the density of air it would be m/d to get the volume
And yes you would need a better scale

Although it is a simple machine I believe that you should find the height of the escalator, you already have a hypotenuse, right angle and another angle (31). And with two angles you know the other...

There is probably a formula but it will be big or have crazy fractions

You mean the ones such as
There are 24H in a D
There are 24 hours in a day
Or
1000MM are in a(n) M
1000 millimeters are in a meter

YTMND - Breakup Letter, Dramatic reading

NOTE: this won't scare you are anyting

think of it, find the algebraic value first
1,4 to 2.8 is slope of 4 y intercet of 0,0 so y=4x
5,2 to 5,6 is slope of infinite (vertcal) y intercept of 0,5 so x=5
so, now find y=4x with x=5 and...

Ok, #2 is in terms of y right?
So
r=5z
15z=3y
since 15/5=3 you can substitute 15z for 3r, now
3r=3y
divide by 3
r=y
now #1
12 to 19

First divide by -8 on both sides
Now take away the abs. value symbol but have the opposite side be negative and positive, two equations may help.
Now solve.

Why does every other riddle about a letter or "nothing"

x^3
7^3

If you want to know the main facts of this linear equation, use the distributive property (division) to get:
y=(3/8)x+7/8
so
the slope is 3/8 and the y intercept is 7/8
(mx+b)

let's say you have a linear equation that is 5x-2
with mx+b you know that m(5) is the slope and b(2) is the y intercept
now, solve 5x-2=0 or 2/5 is the x intercept
now you know all the main parts...

Hello and calling all frequent mathematics posters, is there any easier way to create math symbols than all that slashing and memorization:confused:

Good way

You used quiet in your response right, well quiet means soft, the word you are looking for is quite

Sorry

Totally correct Perito and Unknown008, elscarta got E to AB
Here is how I do it:
Create a triangle with the points (perito's graph)
see that 5, 12, and 13 makes a right triangle
understand that E...

LCM is the least common multiple usually referring to 2 numbers.
A way to find LCM is to get both numbers' prime factorization.
Now write the numbers in common below (the two #s count as one)....

Here is one of my most favorite questions for Mathcounts, a national math compitition:

If you are still lost

OK

By multiply I believe you mean use the distributive property

Guessing that you are taking 9th grade math, here is how you do it:
for simplifying radicals find perfect square factors of what's under, and multiply what's left by its square root

That's it shihouzhuge! But quiet is a homophone and quite sounds the same way. Quite means what you used multiple times in your response and quiet means soft.
Good job

On is one, sorry

Ok, first of all lets think about 1/3 of the problem
Lets say you put 4 on both sides and they are equal
Then you have 4 unknown balls
Now, you weigh two unknown balls with two "100% equal" balls...

Try again, and if that doesn't work Google Curious Village heavier or lighter, it is the answer to your question

Seriously, proven fact, not even the relatives of ancient Mayans in South America believe the world will end in 2012
WHY WOULD ANYONE BELIEVE THE WORLD WILL END IF THERE IS NO EVIDENCE FOR IT
