Hints-

some may not apply, figure out what ones do: inverted, backwards, binary, hex, letters

Answer 1

The answer is

Hello, world!

The trick is

to divide into 8 bit binary, invert them, and convert to ASCII

As follows:

1011 0111 -> 0100 1000 -> H
1001 1010 -> 0110 0101 -> e
1001 0011 -> 0110 1100 -> l
1001 0011 -> 0110 1100 -> l
1001 0000 -> 0110 1111 -> o
1101 0011 -> 0010 1100 -> ,
1101 1111 -> 0010 0000 -> space
1000 1000 -> 0111 0111 -> w
1001 0000 -> 0110 1111 -> o
1000 1101 -> 0111 0010 -> r
1001 0011 -> 0110 1100 -> l
1001 1011 -> 0110 0100 -> d
1101 1110 -> 0010 0001 -> !
