Answer:
(a+b,c)
Step-by-step explanation:
Note that the midpoint formula is:
Point A (0,0) and Point C (2a+2b,2c)
It follows that:
We are given that there are a total of 78 students. If we set the following variables:
Then, the sum of all of these must be 78, that is:
Since there are 15 in chemistry and physics and 47 in chemistry, we may replace that into the equation and we get:
Simplifying:
Now we solve for P by subtracting 62 on both sides:
Therefore, there are 16 students in physics
