First your list of pseudorandom numbers between 0 and 1

n = 100;
lis = RandomReal[{0, 1}, {n, 2}];

And here is three ways to get what you search for

sol1 = (#1[[1]] + 2*#1[[2]] & ) /@ lis;

sol2 = lis /. {x_Real, y_Real} -> x + 2*y;

sol3 = Apply[#1 + 2*#2 & , lis, 1];

(*Check*)

sol1 == sol2 == sol3
True

Dimitris
