Answer:
$47.50
Step-by-step explanation:
You just take $380 and divide it by 8 hours to get the amount of money per hour, which is $47.50 .
X= a number
29 - 2x= 21
subtract 29 from both sides
-2x= -8
divide both sides by -2
x= 4
CHECK:
29 - 2x= 21
29 - 2(4)= 21
29 - 8= 21
21= 21
ANSWER: The number is 4.

Answer:
135 cent
Step-by-step explanation:
Given that:
Cost of electricity = 10cent / 1 kilowatt hour
TV consumption = 150watt per hour
Duration = 3 hours
Cost of operating for 30 days
Total energy usage per day: (150 watt/hr) * 3 hours = 450 watts = 450/1000 = 0.45kW
Total energy for 30 days = 0.45 * 30 = 13.5 Kilowatt
Cost per kilowatt = 10cent
13.5 kw = 13.5 * 10 cent = 135 cent
135 cent = $1.35
