Step-by-step explanation:
4(5x-2) = 2(9x+3)
20x-8 = 18x+6
20x-18x = 6+8
2x=14
x= 14/2
∴ x= 7 [ANS]
C=10
Here’s how you solve it!
First multiply both sides by 2
Your equation will then look like this:
3c➕46=76
Then move your constant to the other side and when you do this you also have to change the sign
3c=76-46
Then subtract 76 and 46 which is 30
3c=30
Then you divide both sides by 3
c=10
Then you are left with your answer:
c=10

Answer: Hello there!
A model to see the growth of a certain population is the exponential model.
If the initial population is P, then the model can be written as
Where t is the time, and r is growth rate.
and f(0) = P
Then we want to know the time needed for the initial population to be doubled, this is f(x) = 2P, where x is the time that we want to find.
then
then x= ln(2)/r
