36 blue marbles


Step-by-step explanation:

its blue to yellow

3 is blue, 5 is yellow

when you have a ratio you can also say

ex. 3x+5x=y (y in this case is total marbles)

5x=60 then

so x=12

plug it in

3(12)=36

okay man. This is it.

60 yellow marbles.
X blue marbles.

blue:yellow (3:5)


[tex] \frac{60}{x} = \frac{5}{3} [/tex]
Therefore,

[tex]5x = 180[/tex]
[tex] \frac{5x}{5} = \frac{180}{5} [/tex]
[tex]x = 36[/tex]
