The correct equation is:
Start Fraction n over 2 End Fraction equals 120
So, at 8:00 a.m., there were 240 bacteria.
Responses
n2=120; at 8:00 a.m., there were 240 bacteria.
Start Fraction n over 2 End Fraction equals 120 ; at 8:00 a.m., there were 240 bacteria.
2n=120; at 8:00 a.m., there were 60 bacteria.
2 n equals 120 ; at 8:00 a.m., there were 60 bacteria.
n2=120; at 8:00 a.m., there were 60 bacteria.
Start Fraction n over 2 End Fraction equals 120 ; at 8:00 a.m., there were 60 bacteria.
2n=120; at 8:00 a.m., there were 240 bacteria.
2 n equals 120 ; at 8:00 a.m., there were 240 bacteria.
Start Fraction n over 2 End Fraction equals 120
So, at 8:00 a.m., there were 240 bacteria.
Start Fraction n over 2 End Fraction equals 120
Therefore, at 8:00 a.m., there were 240 bacteria.
n/2 = 120 (Multiply both sides by 2)
2*(n/2) = 2*120
n = 240
So, at 8:00 a.m, there were 240 bacteria. Therefore, the correct answer is "n2=120; at 8:00 a.m., there were 240 bacteria."
