From 12x ­- 6y + 9z subtract -x­ -3z + 6y . a) 12z ­- 13x -­ 12y b) 13x + 12y + 12z c) - ­13x -­ 12y ­- 12z d) 13x -­ 12y + 12z

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
