In your question where as the amount of gasoline that 80 drivers bought to fill their cars gas tanks is shown in your diagram and the problem as to find how many drivers bought more than 12 gallons and the best answer would be 36. I hope you are satistfied with my answer and if you need some clarification, please feel free to ask for more
A coefficient is a number that is attached to a term.
For example:
3x² - 5x + 6 = 0
The coefficient of x² is 3.
The coefficient of x = -5.
Hope this explains it.
So you know the whole line is XZ which is 83.Then you find out it is in two parts so that is XY and YZ which are 11 and 4c. You can make the equation:
11+4c=83
4c=72
c=18
c=18 and YZ=72
