Answer:
The answer for this question would be 85 and 17/20 or /20
Step-by-step explanation:
You must first find the LCD of these terms (everything that is separated by the addition signs).
The LCD is 20 because:
2 x 10 = 20
5 x 4 = 20
4 x 5=20
and there is no number lower than 20 that all of these numbers share in their multiplication table.
Now you must multiply every term by the number you used to make its denominator 20. Since 2 x 10 = 20, the new term would be:
60 10/20
Since 5 x 4 = 20, the new term would be:
4 12/20
Since 4 x 5 = 20, the new term would be:
20 15/20
Now we put all the whole numbers and numerators together to get:
60 + 4 + 20 = 84 - whole numbers
10 + 12 + 15 = 37 - numerators
84 37/20 = 85 17/20 or 1717/20
All you need for a point to be left unchanged is it being on the line of reflection. (Generally speaking)
The first one is wrong cause you can have a line of reflection anywhere. If the line is horizontal ( x axis) then the slope would be zero. Whereas a line on y axis would be an undefined slope. There are also diagonal lines of reflections which have slopes
I am pretty sure the second one would be correct because, as previously stated, all the line needs to stay in the same place is it being on the line of reflection.
Again, lines of reflection do not have a set slope, a diagonal line of reflection going like / on the chart through the axis could have a slope of one, but it is not needed for the point to remain in the same place
The point does not necessarily need to be on the origin, it can be anywhere on the line of reflection, and if the line of reflection does not pass through the origin, a point on the origin would be moved in a reflection.
I hope this makes sense and helps you out a bit... have a good day

Step-by-step explanation:
Answer:
Step-by-step explanation:
Given:
A car starts with a dull tank of gas
1/7 of the gas has been used around the city.
With the rest of the gas in the car, the car can travel to and from Ottawa three times.
Question asked:
What fractions of a tank of gas does each complete trip to Ottawa use?
Solution:
Fuel used around the city = 
Remaining fuel after driving around the city = 1 -
= 
According to question:
As from the rest of the gas in the car that is 
, the car can complete 3 trip to Ottawa which means,
By unitary method:
The car can complete 3 trip by using = tank of gas.
The car can complete 1 trip by using = 
=
= 
= tank of gas
Thus, tank of gas used for each complete trip to Ottawa.
