Step-by-step explanation:
The equation is given by :
63.25=800r+3.50
Here,
63.25 is the electric company charges
3.5 is an administrative fee
800 is charge per kilowatt hours
r is rate per kilowatt hour
In this proble, we need to tell that what does r represents. Hence, r shows kilowatt per hour.
We can solve it as follows :
63.25-3.5=800r+3.50-3.50 (Subtracting 3.50 to the both sides)
59.75=800r

Answer:
The expression is 20 - 50/5
Step-by-step explanation:
First we have the quotient of 50 and 5.
This is written as:
50/5
And we know that this is equal to 10, but let's leave it as 50/5 for now.
Now we subtract this FROM 20, then we have the number 20, and we subtract 50/5 from it, this is written as:
20 - 50/5
Now we can also solve this:
20 - 50/5 = 20 - 10 = 10
