Answer:</h2>
Prediction for the number of unsuccessful rolls is 15.
<h2>
Step-by-step explanation:</h2>
There is chance of rolling number 6 on the cube. If we want to find out what is the prediction for rolling number 6 in 18 rolls, we need to multiply which is 3. So if we roll a cube 18 times, we will probably got number 6 three times. When we subtract 3 from 18 (18-3), we get 15. That is the answer to your question.

Answer:
48
Step-by-step explanation:
G:B Total
3:4 7
36 divided by 3 is 12.
12 x 4 = 48
In total there are 84 tokens in the bag, 48 of which are black and 36 are green.
x + y = -9
x + 2y = -25
Rewrite the first equation as x = -9-y
Relace x in the second equation:
-9-y + 2y = -25
Simplify:
-9 +y = -25
Add 9 to both sides:
y = -16
Now you know y,, replace y in the first equation and solve for x:
x -16 = -9
Add 16 to both sides:
x = 7
Answer: x = 7
