The answer is: 41.256 (You round it to the number that you're required to round it)
To get r you have to divide:
-8r=64
----------
-8
You would divide by -8 because you are trying to get r by itself and make sure when you divide one side divide the other one:
-8r=64
---------- r= -8
-8
You would get -8 when you divide 64/-8 because a negative and a negative gives you a positive hope this helps a bunch :)))))

Answer:
C. Roanoke, Alexandria, Norfolk
Step-by-step explanation:
Lets expand all of the numbers
Alexandria 136,000
Norfolk 229,000
Roanoke 91,500
Using these number we can easily see that the order is "Roanoke, Alexandria, Norfolk"
I don't understand when you say "Please answer with two answers!" because only one answer is correct
First you set up a proportion:
7% = 7 / 100
7 x
----- = --------
100 45.50
then cross multiply:
100x = 7 ( 45.50 )
multiply:
100x = 318.5
then divide:
100x 318.5
------- = -------
100 100
x = 3.185
then add x to original price:
45.50 + 3.185 = 48.685
round to hundredths:
48.69 is your answer
