Answer:
O 9.25
Explanation:
The following mathematical equation is given in this question:
5x + 2y = 20
Using this equation, we're asked to find the value of y when x = 0.3. Hence, we substitute 0.3 for x in the equation as follows:
5x + 2y = 20
5 (0.3) + 2y = 20
1.5 + 2y = 20
Collect like terms
2y = 20 - 1.5
2y = 18.5
Divide both sides by 2
y = 18.5/2
y = 9.25
Therefore, y = 9.25 when x = 0.3
Answer:
Total 495 liters of natural oil are needed.
Explanation:
It is given that 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.
It means the ratio of natural oil and synthetic oil is
Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.
It means the ratio of natural oil and synthetic oil is
Equate both ratios,
On cross multiplication we get
Divide both sides by 8.
Therefore total 495 liters of natural oil are needed.
When fat enters the small intestine, fat digestion occurs. This is where most nutrients are consumed, too. Enzymes that break down fats, carbohydrates, and proteins are formed in your pancreas. The bile that helps you digest fats and certain vitamins is formed by your liver.
