Answer:
If there are 5000 bacteria in a colony right now, there will be 5000x2, or 10000 bacteria in the colony in 37 minutes.
If there are 10000 bacteria in the colony in 37 minutes, there will be 20000 bacteria in the colony in 74 minutes, as the bacteria doubles every 34 minutes.

What i don't understand sorry I couldn't help because im only in 5th grade im sorry
3 × 100 = 300
the easiest way to do it is just add the same amount of zero's to the number you multiplied with. for example
3 × 10000 if you would just take out the zero's
it would look like this. 3 × 1
the answer of course would be 3 then you can put the zero's back in the answer (30000)
at least that's how I understood it
3 × 100 =
3 × 1(00) =
-->
-->
(00)
3 × 1(00) = 3
3 × 100 = 300
You are not dumb. No one is dumb. Einstein failed math in high school.
Anna is x years old.
Jane is y years younger.
This means the Jane is x - y years old.
In three years, Anna will be x + 3 years old.
In three years, Jane will be (x - y) + 3 years old.
Let S = the sum of their ages in 3 years.
S = x + 3 + (x - y) + 3
S = 2x + 6 - y
Got it?
