Answer:
Step-by-step explanation:
Remark
We have to assume that the die is a cube.
We know that getting a 3, if the die is fair, is 1 chance out of 6 = 1/6
We don't know how many blues there are on the spinner, but we do know that the number of them is over 20. So that's x/20
Now multiply the left side to get the combined probability. x/20 * 1/6. The result is 10.83/ 100
Solution
(x/20) * (1/6) = 10.83/100
x / 120 = 10.83/100 Multiply both sides by 120
x = 10.83 * 120 / 100
x = 12.996 which is going to round to 13
The blue spaces = 13
Answer:
9m+6m^2n
Step-by-step explanation:
12mn-3mn=9mn
4m^2n+2m^2n=6m^2n
==> 9m+6m^2n
or rewrite as 3m(3+2mn)
