-8x+6+10x=-4 solve for x

2x=-4 -6

2x= -10

x= -5

You are welcome :)

Okay. Thanks :)

Same way I just did on the first one :)

How would you show work for 8.25 by 3.375?

Which corresponds to an angle of 53.13 degrees

how to divide 2.25 by 3.375

2.25/3.375

=0.66666666

Cos=9/15

Cos=0.6

8x+6+10x=-4 solve for x

-8x      -8x

-------------------

6+2x=-4

-6       -6

----------

2x=2

x=1

:)

we use math EVERYDAY. Math helps you balance out your money. :)

MAth is great to use in life!

Ich bin mit Google Translate , aber sie war nur , dass zu sagen . Sie hat nichts zu bedeuten , indem sie es .

I take it you don't speak English??

(-9/5)^0 = 1

Na und ?

What is -9/5 to the 0 power

=-1

:)

Guest beat you to it, Asinus! :)

x = 2y - 4

x + 8y = 16

2y - 4 + 8y = 16

10y = 20

y = 2 

x = 2y - 4

x = 2*2 - 4

x = 0

!

Solve the following system: {x = 2 y-4 x+8 y = 16 Substitute x = 2 y-4 into the second equation: {x = 2 y-4 10 y-4 = 16 In the second equation, look to solve for y: {x = 2 y-4 10 y-4 = 16 Add 4 to both sides: {x = 2 y-4 10 y = 20 Divide both sides by 10: {x = 2 y-4 y = 2 Substitute y = 2 into the first equation: Answer: | | {x = 0          y = 2

I'm not sure why. But you can just do this ..

" 4/3 "

None. That's gross!!

pH | 11.22

pH = -log_10([H^+]) | 
[H^+] | hydrogen ion concentration
(assuming hydrogen ion concentration is in moles/liter)

Would it be..

X=-1?
