Answer:
it should be 17.9, I don't really know how to explain it I'm sorry-
It is 9 because 11 minus 2 is equal to 9.
1.) -15.9, -15.2, -3.6, 3.6
2.) second one is already correct
3.)-2.3, -2.03, 2.03, 3.0
The answer would be B.52 because, when you divide 104 by 78 you get about 1.333333. Which is the number you also use to multiply 39 by to find X. hope this helps!!!
