60%

Step-by-step explanation:

percent of green marbles = (total number of green marbles / total number of marbles in the bag) x 100

total number of marbles in the bag = 30 + 20 = 50

30 / 50 x 100 = 60%

$q=\frac{h^{2}-k^{2}}{3m}$
Cross-multiplying and rearranging, we get:
$k^{2}=h^{2}-3mq$
or written without using latex:
k^2 = h^2 - 3mq
Can you finish now?
