<em />
Step-by-step explanation:
Given
![Rent = 1800](https://tex.z-dn.net/?f=Rent%20%3D%201800)
![Gas = 150](https://tex.z-dn.net/?f=Gas%20%3D%20150)
monthly
![Number\ of\ Roommate = 5](https://tex.z-dn.net/?f=Number%5C%20of%5C%20Roommate%20%3D%205)
Required
Determine the electricity bill
If each roommate pays 425, then 5 roommates pay 5 * 425
![Total = 5 * 425](https://tex.z-dn.net/?f=Total%20%3D%205%20%2A%20425)
![Total = 2125](https://tex.z-dn.net/?f=Total%20%3D%202125)
This implies that: the monthly cost of room, gas and electricity add up to 2125.
In other words,
![Gas + Rent + Electricity = 2125](https://tex.z-dn.net/?f=Gas%20%2B%20Rent%20%2B%20Electricity%20%3D%202125)
![150 + 1800+ Electricity = 2125](https://tex.z-dn.net/?f=150%20%2B%201800%2B%20Electricity%20%3D%202125)
![1950+ Electricity = 2125](https://tex.z-dn.net/?f=1950%2B%20Electricity%20%3D%202125)
![Electricity = 2125 - 1950](https://tex.z-dn.net/?f=Electricity%20%3D%202125%20-%201950)
![Electricity = 175](https://tex.z-dn.net/?f=Electricity%20%3D%20175)
<em>Hence, the electricity bill is 175</em>
Commutative property of multiplication
Step-by-step explanation:
The average speed is distance over time.
34 mi / 0.5 hr = 68 mph
Therefore, the driver must have been speeding at some point between the two toll booths.
Y/22 would be the answer to your question.
X=4 and y=6
For this, you should use simultaneous equations
