A bag contains yellow, green, blue, and white marbles.  The ratio of yellow, green, blue, and white marbles is 1:2:3:4.  If the bag contains 180 marbles, then how many blue marbles are there?  

Consider:  "The ratio of yellow, green, blue, and white marbles is 1:2:3:4."  

Call the number of yellow marbles X.  

So the number of green marbles is 2X. 

And the number of blue marbles is 3X.  

And the number of white marbles is 4X.  

Add up all the marbles and you have     10X  =  180  

Therefore                                                   X  =  18 yellow marbles  

                                                                 2X  =  36 green marbles  

                                                                 3X  =  54 blue marbles  

                                                                 4X  =  72 white marbles

Hope this helps!

Thanks, I think I might be able to solve the next promblem.

This also helped alot with my promblem too,

Thanks.

It's the opposite if this promblem

The promblem is \(\sqrt{12-\!\sqrt{12-\!\sqrt{12-\cdots}}}\)

\(\mbox{draw[blue, very thick] (0,0) rectangle (3,2)}\)Thanks, now I get it. 

Well the next promblem is

  \(\sqrt{12-\!\sqrt{12-\!\sqrt{12-\cdots}}}\)

Thanks for the help!

I have no Idea of what to do.

I need help fast!!!

Good try but the answer was 30.

It says this:

There are no values of \(x \) that make the equation true.

No solution

I recommand you try to use mathway to solve this.
