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
x = 26
Because 26-2=24 which would be right because it needs to equal the same size as the other side that is across from it.
y = 11
Because it’s the same size as the bottom side, which is also the side across from it.
This is true because a parallelogram has 2 sets of parallel side!!!
I hope this helps! :)
