slow down bro. 

Can't you learn that the answer has already been asked?

Nice job.

What are you guys even talking about?

The answer was a blackboard. 

This is going to be the ultimate troll for people who think that people are hw cheaters. xD

Actually, in a few days. I'm to lazy to wait that long. 

Hmmm. So, we can see that there are 16 white socks and 2 black socks. There are 18 socks in total. 16 / 18 that he draws white. Then, we multiply 16 / 18 by 2 / 17. It is 2 / 17 instead of 2 / 18 because we already taken a white sock. When we multiply them together, we get 16 / 153. Then, we do it the other way around. We have a 2 / 18 chance of getting a black sock. Then, we have a 16 / 17 chance of getting a white sock. When we multiply them together, we get 16 / 153 again. Therefore, we multiply 16 / 153 * 2, or 32 / 153.

Or, you can see this(This is a copy paste of what was on Brainly):

One bagel costs 155 cents.

---------------------------------

This question is solved using a system of equations.

I am going to say that:

x is the cost of a toast.

y is the cost of a bagel.

z is the cost of a muffin.

---------------------------------

Two pieces of toast and a bagel costs $3.15.

This means that 

Since we want to find the cost of a bagel, we write x as a function of y, so:

---------------------------------

A bagel and a muffin costs $3.30.

This means that:

Since we want y:

---------------------------------

Piece of toast, two bagels and three muffins cost $9.15.

This means that:

We have x and z as functions of y, so:

---------------------------------

In cents, one bagel costs 100*1.55 = 155.

Where did all the comments go? It's obviously 5. 40 is 2 x 2 x 2 x 5.
