Step-by-step explanation:
We estimate that 12/480=1/40 fish are tagged, so 600 is 1/40 of the total number of fish. This means that there are about 600*40=24000 fish total in the pond.
Hold on I’m not answering but do you do FLVS school?
0.25[2.5x+1.5(x-4)]=-x
0.25(2.5x+1.5x-6)=-x
0.25(4x-6)=-x
x-1.5=-x
2x-1.5=0
2x=1.5
x=0.75
