Answer:
4x
Step-by-step explanation: slope
Using the the density(D)-mass(m)-volume(V) formula

, we can calculate the volume
Answer: -96r + 13
1. distribute 8x2 - 8x12r
-3+8(2-12r)
-3+16-96r
2. add constants -3+16
-3+16-96r
13-96r
3. standard form
-96r + 13
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.
