Angle x is (2n+12) and angle y is 3n+18 find the measure of angle x

I have a solution.

Step-by-step explanation:

(2n+12) and 3n+18

=2n+12=3n+18

=2n+3n=12+18

=5n=30

=n=30÷5

=n=6

therefore,x=n=6

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
