Harriet is cultivating a strain of bacteria in a petri dish. currently, she has 10^3 bacteria in the dish. the bacteria divide every two hours such that the number of bacteria has doubled by the end of every second hour. how many bacteria will harriet have in the dish at the end of 6 hours?

A=P(2)^(t/d)
A=future amount
P=starting amount
t=time elapsed
h=doubling time

given
P=10^3
t=6
d=2

A=10^3(2)^(6/2)
A=10^3(2)^2
A=10^3(4)
A=4*10^3
A=4000

4000 bacteria

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
