What is the equation for variable y 6x-12y=18 ?

If you solve for y, it is equal to 1/2x - 3/2

In order to find this, follow the order of operations to isolate y.

6x - 12y = 18 > subtract 6x from both sides

-12y = -6x + 18 > Divide by -12

y = 1/2x -3/2

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
