Answer:
x=2
Step-by-step explanation:
-3*(x-2)-(2*x-3)-(5-(4*x-2))=0
((0 - 3 • (x - 2)) - (2x - 3)) - (7 - 4x) = 0
2 - x = 0
-x+2 = 0
Subtract 2 from both sides of the equation :
-x = -2
Multiply both sides of the equation by (-1) : x = 2
Answer:
5,120 bacterias
Step-by-step explanation:
Given the amount of bacteria after x hours modelled by the equation:
f(x) = 20(2)^x/12
Note that x is in hours not days
To calculate the number of bacteria that will be contained within the culture after 4 days, we will first convert 4days into hours since x is in hours.
24hours = 1day
xhours = 4days
x = 24×4
x = 96hours
Substituting x = 96 into the equation
f(96) = 20(2)^96/12
f(96) = 20(2)^8
f(96) = 20×2^8
f(96) = 20×256
f(96) = 5,120
The number of bacteria that will be contained after 4days is 5,120bacterias
Answer:
A = 20
Step-by-step explanation:
12/3 = A/5
60 = 3A
A = 60÷3 = 20
