The correct equation is:
n/2 = 120
This equation represents the number of bacteria, n, at 8:00 am. If we solve for n, we find that n is equal to 240 bacteria. Thus, there were 240 bacteria at 8:00 am.
A culture of a certain bacteria doubles every hour. At 9.00 am, there were already 120 bacteria. Which equation represents the number of bacteria, n, at 8:00 am? How many bacteria were there? (1 point)
O 2n = 120 at 8.00 a.m., there were 60 bacteria.
pi/2 =120| at 8:00 am, there were 240 bacteria.
2n = 120 at 8:00 am, there were 240 bacteria.
n/2 = 120 at 8:00 am, there were 60
