Hello
I have done this before and Nothing further can be done.
Hope this helps
Answer:
x = 16 because if you multiply that and then divide
If its on a graph just look for the spot where the line meets the y and x-axis

Precision goes up as you have more decimals. It gives you a more accurate measurement regardless of what it is measuring.
A line graph measures two variables, the X and the Y, and how they change based off of one another
And an educated guess would usually based on previous trends or results
