Answer:
Hi there!
6/15 is the probability that the marble is black!
Step-by-step explanation:
Oki, so lets's find the total number of marbles first!
8 + 6 + 1 = 14 + 1 = 15
And just turn it into a fraction!(very simple and easy)
6/15
28 = w/4 + 16....subtract 16 from both sides
28 - 16 = w/4
12 = w/4....multiply both sides by 4
12 * 4 = w
48 = w <===
Atomic number cannot be same and also atomic number can also be called an unique ID of an element.
Multiply both sides by -1
|-x|=12
-x=12
x=-12
-x=-12
x=12
Final answer: D
