If 9x + 2a =ac - bx, then x equals

Step-by-step explanation:

9x + 2a = ac - bx

9x         = ac - bx - 2a    subtracted 2a from both sides

9x + bx = ac - 2a           added bx to both sides

x(9 + b) = a(c - 2)           factored out x from the left and a from the right

           divided both sides by 9+b

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
