What is the most efficient first step to isolate the variable term on one side of this equation?
-9x = -4x + 5
Subtract 5 from both sides.
Add 5 to both sides.
Subtract 9x from both sides.
Add 4x to both sides.

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.
