You start by figuring out how to get rid of the 13. To get rid of positive 13 (if there is no symbol before it, it's positive) you subtract 13. You have to then subtract 13 from anything on the other side of the equal sign that is a constant (a number that has no variable beside it) being 31. The answer is 18.

13+b=31

-13      -13

b=18

Thanks for that answer, Summerkim12......welcome to the forum.....!!!

what equals 57 but you can only use 1,1,2,3,5

Here is one way:

(5! / 2) - 3-1+1

(120/2) - 4+1

60 - 3=57

2.5 x 10 = 25.0

We know an angle and the opposite side of a right triangle....and we're looking for the adjacent side ....so......We can use the tangent for this :

tan (26.3) = 93 /  d    where d is the distance to the base.....re-arrange...

d = 93 / tan(26.3)  = about 188.17  m  = 188 m  rounded

i want to m****r my geography teacher literally . i want her to die

The asterisks stand for m.u.r.d.e.r      Just in case you didn't get it!.

Naw.....I think that is the theme song from 'Bonanza'

You divide 11  'BY'  25   

enter '11'    then the division symbol  then 25  then =

She will....probably LONG before you.....unless you do something stupid.

Start by ADDING 4.5 to all three sections to get

-17.76 > 4.8x >  - 27.84       now divide  all three sections by 4.8 to get

    -3.7  >    x   >   -5.8

5  it is

Sure !

3^3 = 27 in the numerator so you have:

27/3^y = 1/9   multiply both sides by 9

243/3^y = 1     Now multiply both sides by 3^y

243=3^y         Now take the log of both sides

log 243 =  log (3^y) = y log 3    Now divide both sides by log 3

log 243  /  log 3  = y       NOw use the calculator   to find y = 5

Solve for y over the real numbers:
3^(3-y) = 1/9

Take reciporicals of both sides:
3^(y-3) = 9

Multiply both sides by 27:
3^y = 243

243 = 3^5:
3^y = 3^5

Equate exponents of 3 on both sides:
Answer: | y = 5

We have the following inequality - where p is the number of packs ordered

20p + 10 <= 120

20p <= 110

p<= 5.5       round down to 5

D is the correct answer  [ although I question whether ordering 0 packs makes sense ...!! ]

My guess is santorum......look it up

brah that is awesome

Infinite.

' Five Factorial'   is  5!  =  5 x 4 x 3 x 2 x 1 = 120

h0I 

i'm temmie

 it's me 
I was wondering if after all these years you'd like to meet 
To go over everything 
They say that time's supposed to heal ya
But I ain't done much healing

Hello, can you hear me?
I'm in California dreaming about who we used to be
When we were younger and free
I've forgotten how it felt before the world fell at our feet

There's such a difference between us
And a million miles

Hello from the other side
I must've called a thousand times 
To tell you I'm sorry
For everything that I've done
But when I call you never 
Seem to be home

Hello from the outside
At least I can say that I've tried 
To tell you I'm sorry
For breaking your heart
But it don't matter, it clearly 
Doesn't tear you apart anymore

why does this site put asterisks in m****r. is not even a bad word

Hit the  '2nd' button in the upper left corner...then the' tan' key will become' atan'   which is inverse tan

whoa whoa whoa no need to go that far man!

Each row will have an odd number of dancers where a successive row has two more than the previous  one.......

The sum of the first N odd numbers =  N^2

So.....we want to know when........

N^2 <= 25

N <= 5

So....we need 5 rows
