Answer:
To answer the question above, we need to know about the rules of mixed count operation. In mixed count operation, we can find plus [+], minus [-], divided [:], multiplication [x] and parenthesis [(...)]. For example, if the operation is: 7 x 5 + 3 - (4 x 3) : 6 = ...
first, we must finish the operation inside the parenthesis symbol, which is (4 x 3), the result is 12
second, we must finish the operation with the multiplication or divided symbol but, if both exist we must finish the far left-side first. for this example is to finish "7 x 5 = 35" first, then finish the next operation with divided symbol "(4 x 3) : 6 = 12 : 6 = 2"
for the last, we finish the operation with plus or minus symbol, but if both exist then we must finish the far left-side first. For this example is to finish "35 + 3 = 38", then finish the next operation which is "38 - 2 = 36".
there are the rules of mixed count operations, to make it clear we finish the example operation step by step
7 x 5 + 3 - (4 x 3) : 6 = ...
7 x 5 + 3 - 12 : 6 = ...
35 + 3 - 12 : 6 = ....
35 + 3 - 2 = ...
38 - 2 = 36.
now the answer to the mixed count operation above 20 : 2 (5 + 5) = ...
20 : 2 x (5 + 5) = ...
20 : 2 x 10 = ...
10 x 10 = 100
the answer of the operation is 100
