There are 7 red, 8 green, and 6 blue marbles
in bag. kate is going to select one marble at
random. what is the probability that she will
select a green or blue marble?

14/21

Step-by-step explanation:

Total marbles = 7+8+6 = 21

7 Red

8 Green

6 Blue

Probability of choosing Red = 7/21

Probability of choosing Green = 8/21

Probability of choosing Blue = 6/21

Probability of choosing Green or Blue = 8/21 + 6/21 = 14/21

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
