b = (T - a - c - d) / 3
Step-by-step explanation:
Let T be the total number of points required to advance.
a, c and d are points scored in the local matches, and b is the number of points scored in the district match. If b is worth 3 times as much as the other matches, the total number of points is given by:
Isolate b in order to find out how many points they need in the district match:
They need to score (T - a - c - d)/3, in the district match in order to win.
Here for 120, the expression for the start root and end root is given
Here we need to find
By simplifying the given expression, we get:
by taking square roots on both sides we get
Thus for 120, the expression for the start root and end root is given
