Answer:

1) -95.

2) 15.

3) The conference center is on floor 5.

Explanation:

1) Evaluating gives
-52-30-13=-(52+30+13)=-(95)=-95.

2) Substituting gives
x+27=(-12)+27=15.

3) After going 4 floors down, we are on level -4. After going 9 floors up to the desired room, we are on level -4+9=5. So the conference center is on floor 5.
