Ummm there’s no right triangular
Answer:
$55.902
Step-by-step explanation:
To properly answer the question, we need to evaluate each of the payment conditions.
Firstly:
There is a $6 charge each month
Secondly:
For the first 500kwh, there is a charge of 6.726 cents per kWh.
Total amount charged here will be 500 * 6.726 = 3,363 cents = $33.63
Thirdly:
There is a charge of 8.136 cents for kwh above 500kwh. Here we have 200kwh more than the 500kwh threshold.
The amount charged here is thus 200 * 8.136 = 1627.2 cents = $16.272
Total amount charged is thus : 6 + 16.272 + 33.63 = $55.902
If you need explanation I can explain
The number is "fifteen thousand four hundred nine".
In addition to my normal speech, I can say it in maybe ten different
regional dialects and foreign accents, but none of them really well.
I can also say it in four foreign languages that are not English.
To check if x = 9 is the solution, we need to replace every x with 9 and simplify
(3+x)/4 = 3
(3+9)/4 = 3
12/4 = 3
3 = 3
We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.
