8r+(12-3)p-7------>8r+9p-7
Y-12÷2
because it says 12 less than y we subtract y-12 but then it says divided by 2 so then it is reasonable to say y-12÷2
Divide 4 by both sides
Then you get 4=3+b2
Then subtracts 3 from four
You get 1=b2

Answer:
5, 10, 20
Step-by-step explanation:
Suppose the three numbers are x, 2x, and 4x. Then they have the required ratios. After the transformation, we have ...
((x+3) +(4x -8))/2 = 2x . . . . . 2nd term is average of 1st and 3rd
5x -5 = 4x ⇒ x = 5
The original numbers are 5, 10, 20.
_____
After the adjustment, the arithmetic sequence is 8, 10, 12.
