I believe the answer is 1.
Hope that helps!!!
Lets say for arguments sake that the bag contained 2 blue and 3 red marbles
p:q = 2:3 In order to get a ratio of 2:1 we would have to add 4 blue marbles
(6:3 = 2:1).
So the ratio p to r = 2:4 = 1:2 answer.
Answer:
-27
Step-by-step explanation:
Number be x
Eight added to number: x+8
sum is doubled: 2*(x + 8)
-11 less than number: x -11
2*(x + 8) = x -11
2*x + 2*8 = x - 11
2x + 16 = x - 11
2x - x = -11 -16
x = -27
