A bag has 7 red marbles, 8 blue marbles and 5 purple marbles. Rachel draws a marble from the bag without looking. What is the probability that Rachel draws a blue marble?
O A 45
OB. 8%
O c. 12.5%
D. 405
O E 66.75

40%

Step-by-step explanation:

7+8+5=20

8/20

.40 then move the decimal to the left 2 times and there's your answer

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
