Utilizing the information partially, we can deduce that:
\(\frac{(8+x+y+10)}{(4)} = 12\)
\(x+y= 30\)
manipulating the last euality:
\(y= 30 - x\)
Given that information, and knowing the fact that \(x>y\), replacing the ineuality with the last expression, we have \(x > 30 - x\), and doing some algebra, \(2x > 30\). Therefore, Option A.
