Answer:
When multiply a number by another number and get that number.
45 / 3 = 15
45 - 15 = 30
30 / 5 = 6
6 x 2 = 12
30 - 12 = 18
The answer is D:18
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

If you divide $6.00 by 120, you come up with 5 cents per mile. So the slope of the line (m) would be 0.05, or 1/20.
We also know that it costs $40.00 at 100 miles, so when x=100, y=40. If you multiply 100 by 0.05 you get 5, which means the rate goes up $5.00 for every 100 miles. So if you take your original y=40 ($40.00 for 100 miles) and subtract 5, that means y=35 for 0 miles, and that gives you your zero-intercept (b).
So your equation would be y = 1/20x + 35
Now, if x = 300 miles, then
y= 1/20*300 + 35
y = 15 + 35
y = 50, therefore it would cost $50.00 to drive the rental car 300 miles.
