First you combine like terms. Adding 5n and 4n together to get 9n+3=30. Then you subtract 3 from 30 and end up with 9n=27.
Then you divide 27 by 9 and end up with n=3.
So the answer is 3.

N=3
5n+3+4n=30 (add 5n and 4n)
9n+3=30 (Subtract 3 from both sides)
9n=27 (divide both sides by 9)
n=3

Question 22 Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 8 liters of natural oil for every
Setler [38]

Answer:

897 liters

Step-by-step explanation:

The motor oil is composed of 8 liters of natural oil and 5 liters of synthetic oil. This means there is a ratio of 8/5. We have 552 liters of natural oil to y liters of synthetic. This is the ratio 552/y. Create a proportion that compares the two ratios.

\frac{8}{5}=\frac{552}{y}

Solve by cross multiplying.

8y = 5(552)

8y = 2,760

y= 345

345 liters of synthetic oil.

Together 552+345= 897 liters of motor oil.

What's the difference between using f(2) and f(x)=2?
BabaBlast [244]
F(2) means that you are plugging in 2 for x, while f(x)=2 means that the equation equals 2 (y=2) at a certain x value.
