We are starting with 8+4+7+5=24 marbles. We're taking out 8, so we'll be left with 24-8=16 marbles. Think about those 16. If the probability of drawing a white one is 1 in 4, that means that 1/4 of the marbles are white. 1/4 of 16 is 16/4 = 4 marbles are white. Since we started with 8 white, and there are 4 left, we must have taken out 8-4 = 4 white marbles.

Step-by-step explanation:
1) Convert mixed numbers to decimal numbers dividing the numerator by the denominator and adding the result to Whole number part:

The unit rate is:

2) Divide 2,857 points by 1,487 games:

3) Divide 255 strikeouts by 204 innings:

4) Divide 15 errors by 1,000,000 pieces:

5) Divide 5,979 points by 179 career playoff games:

20 + 17y = -6 + 15y
First, regroup your terms.
Second, take away '15y' from each side.
Third, subtract '17y - 15y' to get '2y'.
Fourth, take away '20' from both sides.
Fifth, simplify '-6 - 20' to get '-26'.
Sixth, divide both sides by '2'.
Seventh, how many times goes 2 go into 26? 26 ÷ 2 = 13.

Answer:
y = -13
