9 I think because 1/4 needs to have 4 of those to be a whole so yeah 9.
Steps to solve:
25 = x + 19
~Subtract 19 to both sides
6 = x
Best of Luck!
One coordinate that is 7 units away from (2,-7) is (2,0). (2,0) is 7 units to the right of (2,-7)
Another coordinate is (9,-7). This one also works.
The decimal in standard form for 12 and six hundredths is 12.06
