So to add fractions they need to have a common denominator, which in this case is 24. then multiply 1 by 4 and 5 by 3 because whatever you multiply the denominator by you need to do the same to the numerator, which will get you 4/24+15/24 then you add across the numerators and you get 19/24
Commutative law: a+b=b+a thats it...
So 9+7 can also be written as 7+9=16
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.
P=i/rt
