Percentage = 
Percentage = 82.35%
Rhion scored 31 out of 39.
Percentage = 
Percentage = 79.48

Answer:
a=2
Step-by-step explanation:
4a-3(a-2)=2(3a-2)
4a-3a+6=a-4
a+6=6a-4
a-6a=-4-6
-5a=-10
divide both sides by -5
a=2
Answer:
4(20+12) / (5-3) = 64
Step-by-step explanation:
The way to solve this problem is simple. Using PEMDAS the obvious thing to do is start with the Parentheses.....
4(20+12) / (5-3)
The way this would look after I use PEMDAS is....
4(32) / (2)
Now there are no exponents so we will now move onto the multiplication section. So we will need to multiply 32 and 4 which will leave us with 128. This now leaves us with...
128/2
Now going on to the last step we will use division since it is our last step we do not need to worry about adding or subtracting. After dividing 128 by 2 it will leave us with the answer of 64. So the answer of the equation is....
4(20+12) / (5-3) = 64
