On a graphing calc hit 2nd then Sin

While Mixed numbers are easier to form than decimals off the top of your head, you should use the decimal .64 as decimals are used more in math.

The mixed number is  

-4( 4 )

   (25)

Hi

im bored

No I don't think that my 2 could equal your 10. While we created the symblos and pronunciations of numbers, unless you were tought that 2 was really 10, it's probably not wrong. If it helps, think about it with physical things. If I have 2 cookies, how could I possibly have 10. along that same line i could never simply make 80 cookies appear by adding 10+10. So unless you were educated to beleive that the number 10 meant the quantity 2 to most everyone else, it's pretty much completely irrational to say that our operations are wrong in our time when communication and globally spreading information is easier than ever. Colors, however, may fit in this question better because one human cannot see through another's eyes, so there is no way for us to know if any human sees the same colors as the one next to him.

were you high when you asked this? no offense if you weren't, but d**n

well

AC=CB

2x+1=3x-4

-2x     -2x

x-4=1

 +4  +4

x=5

AC=2(5)+1

     =10+1

     =11

and because AC=CB

CB=11

CB=3(5)-4

     =15-4

     =11

yes

6²/3(2)+4

36/3(2)+4

12(2)+4

24+4

28

if the equation is 0/1000 the answer is 0

if the equation is 1000/0 the answer is undefined.

These answers are the same for any number substituted for 1000

Use the Pemdas method to solve this

first the parenthasis (-42/7-3(2))

                                  (-6 - 6)

                                     (-12)

then add -3 to -12

answer: -15
