Answer:
n=18
Step-by-step explanation:
100=4(n+7)
100=4n+28
-28 -28
72=4n
n=18
In case this wasn't easy to understand, first you distribute the 4 to the n and 7, to get 28, after that the equation becomes 100=4n+28, then you subtract 28 from 100, and from itself to get the 4n by itself, you are left with 72=4n, after that you just divide 4n and 72 by 4 and get n=18
hope that helped :)
Step-by-step explanation:
If we calculate so there are 120 sec in 2 min
So we will divide 120 by 15 = 8
It means they will be doubled 8 times
So if bacteria are now 10 so 10 × 8 = 80
There will be 80 bacteria in 2 min
