To find the missing number in the equation -540 + _____ = -847, we can set the missing number as ( x ).
So the equation becomes:
(-540 + x = -847).
To isolate ( x ), we can add 540 to both sides:
( x = -847 + 540 ).
Now, calculate:
(-847 + 540 = -307).
So, the correct answer is ( x = -307 ), which corresponds to option D.
