Answer:

-3.7

Step-by-step explanation:

(-y+5.3)+(7.2y-9)=6.2y+n

-y+5.3+7.2y-9=6.2y+n

5.3-9-y+7.2y-6.2y=n

-y+7.2y-6.2y=0 so we will not write the y

n=-3.7

To determine the number of trout in a​ lake, a conservationist catches 180 ​trout, tags them and throws them back into the lake.
GaryK [48]
The ratio of the trout with tags that are caught and the total trout with tags is first calculated.

     r = 12 trout / 180 trout = 1/15

Then, we divide the number of trouts caught without tag by the value obtained above.

     N = (48 - 12) / (1/15) = 540

Then, we add the number obtained above and 180.
     T = 540 + 180 = 720
