Answer:

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.
D because if you do a rate problem you do 50 times what equals 100 so times two then you do 32 times two

Answer: There are 12 pairs of tennis shoes.
Step-by-step explanation:
Since we have given that
For each pair of tennis shoes , she owns 4 pairs of flip flops,
so their ratio will be 1:4
Let the number of tennis shoes be x
Let the number of flip flops be 4x
According to question,
4x-x=9
3x=9
x=\frac{9}{3}
x=3
So, the number of pairs of tennis shoes is given by

Hence, there are 12 pairs of tennis shoes.
