Dx+fy=m, for x.

the solution is x=

So to solve for a variable, we must isolate such variable onto 1 side of the equation. In this case, we must isolate the x variable. Firstly, subtract both sides by Fy:

Next, divide both sides by D:

Your final answer is

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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.
