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.

anastassius [24]

Answer:

it is 0.91<u>6 (</u>the six is repeated. a line under a number means repeated in this case)

Step-by-step explanation:

First you take 3 1/4 and turn it into 13/4 and turn 2 1/3 into 7/3 and transform those into decimals 13/4 = 3.25 and 7/3 = 2.<u>3</u> and subtract which is 0.95 plus the fact that the three is repeated which gets your answer of 0.91<u>6</u> however you should say that if they want you to simplify it to two/three decimals, it is 0.95 but if they want it exact it is 0.91<u>6</u> with the six being repeated

A) .10 d + .25 q = 7.75
B) d + q = 40

Multiplying B) by -.10
B)  -.10d -.10q = -4.0
Then adding this to A)
A) .10 d + .25 q = 7.75
.15q = 3.75

Quarters = 25
Therefore, dimes = 15
***************************************************
Double-Check
A) .10 d + .25 q = 7.75
A) .10 * 15 d + .25 * 25 = 7.75
A) 1.50 + 6.25 = 7.75

Correct!!
