Answer:

a_{n}  = 11 - 5n

Step-by-step explanation:

use the formula

a_{n} = a_{1} + (n - 1)d

-14 = 6 + (5 - 1)d

-20 = 4d

d = -5

a_{n} = 6 + (n - 1)(-5) = 6 - 5n + 5 = 11 - 5n

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.
