Petrolyn motor oil is a combination of natural oil and synthetic oil. it contains 5 liters of natural oil for every 3 liters of synthetic oil. if 255 liters of natural oil are used, how many liters of petrolyn oil will be made?

153 liters of Petrolyn oil

Step-by-step explanation:

This is a proportion to set this up you do the following:

Nat/Syn = Nat/Syn ; 5/3 = 255/Syn

Then you solve this equation by cross multiplication.

(255*3)/5 = Syn

153 = Synthetic(Petrolyn oil)

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
