The answer to this is D.
The tricky part of this question is to determine the relationship between Lee's points and Alex's points.
From the description "Lee scored 25 points" we can be sure that Lee's points are 25. That's the easy part.
Here comes the real question. We need to change "that was 3 more than twice the number of points Alex scored" into an algebraic equation. From "twice the number of points Alex scored", we can know it's 2a, as Alex's points are represented by a and twice means 2 times. From "that's 3 more", we can determine that Lee has a higher point (25 larger than 2a by 3 points). So, Alex need to add a few more points in order to have the same value as Lee did.
Therefore, if we combine everything together, we can get 25 (Lee's points) = 3 + 2a (twice Alex's points plus 3 because Alex has less points). The answer is D.
n=3.6
Do the distributive property to both sides then add 14n to -4n and get 10n then add 8 to both sides to get 36, the u have 10n=36 then divide each side by 10, 10/10 cancel each other then 36/10 = 3.6 so N=3.6

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.
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.
