The correct answer is: D. (-3) + 2 = -1
The other ones result in a positive sum:
A: 7 + (-5) = 2
B: 1 + (-1) = 0
C: (-3) + 4 = 1
Answer:
A
Step-by-step explanation:

Multiply top and bottom, on the top we get 5*1 which is 5 and on the bottom we get 6*2 which is 12.
P C
3 39
4 48
5 57
6 66
9(3)=27+12=39=c
9(4)=36+12=48=c
57=9p+12
-12 -12
45=9p
divide by 9 both sides 45/9=5=p
c=9(6)+12
c=54+12
c=66
Answer:
-1 1/2= 2 lines to the left of -1
1 1/4= 1 line to the right of 1
