Answer:
B = 6
Step-by-step explanation:
1. 4b + 8 = 6b - 4
2. Add 4 to both sides: 4b + 12 = 6b
3. Subtract 4b from both sides: 12 = 2b
4. Divide 12 by 2: b = 6

Answer:
Whoes Joe?
Step-by-step explanation:
<span>W = event where white marble is drawn
B = event where black marble is drawn
The two events W and B are independent. This is because the marble taken out on the first draw is put back into the bag. Since W and B are independent, we can use this rule
P(W and B) = P(w)*P(B)
Use the rule to get
P(W and B) = P(W)*P(B)
P(W and B) = (1/2)*(1/4)
P(W and B) = (1*1)/(2*4)
P(W and B) = 1/8
1/8 is equivalent to 0.125. Use long division or a calculator
0.125 = 12.5% </span>
