Petrolyn motor oil is a combination of natural oil and synthetic oil. it contains 6 liters of natural oil for every 5 liters of synthetic oil. in order to make 847liters of petrolyn oil, how many liters of natural oil are needed?

In a petrolyn motor oil, in every 6 liters of natural, there is also 5 litters of synthetic oil. So, if we put it in a formula, it would be 6x+5x=11x of petrolyn motor oil. If 11x=847 petrylon oil, every x would have 77 litters of petrolyn oil. Then that means that 6x=462 litters of natural, which was needed in the 847 litters of petrylon oil.

is only a line? i think so

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
