Answer:(1).(C) Commutative property.(4).(D) 3(3).(D)  75Step-by-step explanation:(1) Commutative property of addition states that if two number p and q are real. Then, it doesn't matter in which order the numbers are added it will provide the same result. i.e.p + q = q + pTherefore, -8 + (-15) = (-15) + (-8) is an example of commutative property.(2) - (q+14) = (-3) + (-14)[tex]\Rightarrow -q - 14=-3 -14[/tex][tex]\Rightarrow-q= -17 +14[/tex][tex]\Rightarrow-q=-3[/tex][tex]\Rightarrow q=3[/tex](3) -10 + a + (-15) = 50[tex]\Rightarrow a -25 = 50[/tex][tex]\Rightarrow a = 50 + 25 = 75[/tex]
