2z + 3/8 =3 7/8
how do i work out this problem.

Step-by-step explanation:

I will assume you are solving for z. To solve for a variable, we are looking to get it alone on one side of the equals side, and everything else on the other side.

Here's the given equation:

Note, I turned the mixed fraction into an improper fraction. This will make it much easier to work with.

There are two terms on the left side: and . Only one of them has a Z in it, so lets move it to the right side of the equals sign. We can do this by subtracting each side by .

We can then combine like terms:

Then, we can divide each side by 2 to turn 2z into z:

Therefore,

the answer is c.

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.
