Answer 1

Answer:

(1).(C) Commutative property.

(4).(D) 3

(3).(D)  75

Step-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 + p

Therefore, -8 + (-15) = (-15) + (-8) is an example of commutative property.

(2) - (q+14) = (-3) + (-14)

$\Rightarrow -q - 14=-3 -14$

$\Rightarrow-q= -17 +14$

$\Rightarrow-q=-3$

$\Rightarrow q=3$

(3) -10 + a + (-15) = 50

$\Rightarrow a -25 = 50$

$\Rightarrow a = 50 + 25 = 75$
