Arestaurant is making a large amount of salad dressing. the recipe uses 24 ounces of vinegar and 60 ounces of oil. what is the ratio of oil to vinegar in the salad dressing?

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
