Answer:
I believe the answer is A - graph W
Step-by-step explanation:
8 : 6 ...add 7 yellow and it becomes 15:6 when reduced = 5:2
<span>Twice the sum of a number and 3 = 2(n + 3)
</span><span>three times the difference of the number and 3 = 3(n - 3)
so
</span><span>Twice the sum of a number and 3 is equal to three times the difference of the number and 3:
</span>2(n + 3) = 3(n - 3)
2n + 6 = 3n - 9
n = 15
answer
2(n + 3) = 3(n - 3)
n = 15
True.
Since

,

and the solutions are decreasing functions.
