How Do I simplify this?
-3(x + 4y) + 2(x - 2y) + (3x -5y)

=2x - 21y

Step-by-step explanation:

One step at a time

-3(x + 4y) = -3x - 12y

2(x - 2y) =2x - 4y

=-3x - 12y + 2x - 4y + 3x -5y

=2x - 21y

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.
