Four more than seven times a number is the same as twenty less than three times the number

Let's start by setting up our equations.

Let's call the number "x"

So,

The first part can be represented by

And the second part can be represented by

Then we just set them equal and solve

-8 Is the answer

idk bring the function back   im not smart

step-by-step explanation:

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.
