This is a great explanation mathematician  

$$3x + -x + 4 (8x\div 2)\\
=3x + -x + 4 *(4x)\\
=3x + -x + 16x\\
=3x \;-\;x + 16x\\
=3x \;-\;1x + 16x\\
=(3-1+16)x\\
=18x\\$$

x can be any real number except for 0

yes i play oboe. my friends used to joke and call me a dying duck. Now it's just the oboeduck

i have a symbol too

           k                                    just imagine that it has a beak and legs and an eye 

         c

       u

    d

O B O E

(-27+-27)+(-3+-3)+2+18

        ( -54                    +        -6 )                   2    +       18

                       (  -60                               +        2   )     +     18

                                              -58                                  +18= -40

the parentheses are just to make it clearer

hope it helps!

A sinus is a cavity in bone or tissue.

You probably mean sin or sine

But your question still doesn't make much sense  ;)

You can use a calculator to find the sin of an angle.

there is 10mm in 1cm

20mm in 2cm

30mm in 3 cm

so you work it out   

Do not give out personal information on any forum (including this one)

Telephone numbers and addresses should absolutely NOT be given out to strangers on the internet.

Just because someone has spoken to you on a site a couple of times does not mean that they are who they say they are.

f-6    cannot be simplifed unless you are told what f is.     

There are 2.54cm in 1 inch. So, to find out how many inches 59.2 cm is, you divide 59.2 by 2.54.

59.2 ÷ 2.54 ≈ 23.3 inches😎

19 notttt 21.  It's 19. Not 21 that's boys thing, and mine. ITS 19

Our goal is to isolate the variable (In this case, y) completely.

I'll start by adding 3.7y to both sides:

8.17y + 3.7y = 4.2 - 3.7y + 3.7y

11.87y = 4.2

Now, to completely isolate y, we need to divide both side by 11.87.

11.87y/11.87 = 4.2/11.87

Hopefully you can take it from here using the site's calculator (y = 4.2/11.87 is your final problem.)

It's about 4.5

40 is the answer

The answer is 13/55 :)

36- 72, 108

54- 108

so its 108

Yes. But the blade will need sharpened for a fine cut.

240 in cubed 

so how is it going

Yeah I get it

Yeah,but i'm not trying to be mean but this is a place where you ask questions not giving stuff out like a facebook name or something

LOL who knows

It's 21 dahh, who doesn't know that lol 

hahahaha but seriously whats up with that P.S ( Felise GO TO KIK)

seriously its 19
