In a bag of blue and yellow marbles the ratio of blue marbles to yellow marbles is 3: 5 if the bag contains 60 yellow marbles how many blue marbles are there

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

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
