The answer would be -1. ☺️
Ann = 3 CD's
Ann = 2x-3
5 = 2x-3
x= CD's bob has
5 = 2x-3 is the equation
to solve
add 3 to each side
8 = 2x
divide by 2
x =4
bob has 4 CD's, ann has 5
Answer:

Step-by-step explanation:
Here we are given that for every 2 cups of water , Jada is mixing up 4 cups of Apple Juice. Hence it makes a patter which look like this as given under in a tabular format
x y
2 4
6 12
10 20
We are required to find the equation of the relation that exit between this pattern. Assuming them to be the coordinates , we will apply the two point form and find the equation.
Two point form is
-----------------(A)
Where


Putting these values in A and solving





adding 4 on both sides

Answer:
The population in 20 years will be 781.
Step-by-step explanation:
The population of the town can be modeled by the following equation:

In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate, as a decimal.
The initial population of 500 increases by 25% in 10 years.
This means that 
We use this to find r.



Applying ln to both sides




So

What will be the population in 20 years
This is P(20)

The population in 20 years will be 781.
U add it up the answer will be 4833.34 but plz post a pic
