2/10ths because if you add the marbles all together you would get 10 which would be your denominator and 2 would be your numerator because of how many black marbles

2/10 or 1/5 would be your answer. You get this answer by adding together the number of marbles to get a total of marbles, this will be the denominator, the number of black marbles is your numerator. Hope I helped :) If you have any other questions hmu!

How many real solutions does the equation y2− 8y + 16 = 0 have?

saveliy_v [14]

We can solve this equation by completing the square. Notice that $4*2=8$ and $4^{2}=16$ . Therefore, we can turn $y^{2}-8y+16=0$ into $(y-4)^{2}=0$ . y, in this equation, only has one real solution: 4. So your answer would be (B).
