An electric company charges a certain rate per kilowatt-hour (\text{kwh})(kwh) of electricity used and an administrative fee of \$3.50$3.50. the company charged zhao \$63.25$63.25 for using 800\,\text{kwh}800kwh of electricity. zhao uses the equation, 63.25=800r+3.5063.25=800r+3.50 to represent the situation. what does the variable rr represent in the equation

r represents the rate the electric company charges per kilowatt-hour.

Step-by-step explanation:

r represents the rate the electric company charges per kilowatt-hour.

Total charged to Zhao was 63.25 out of which 3.50 is administrative charge (fixed).

Matching the "word equation" with "mathematical equation", we see that 800 is the hours used and r is the charge per kilowatt hour.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
