Iwill give brainliest if correct!
q1) what property is shown?
-8 + (-15) = (-15) + (-8)
a) distributive property
b) opposite of a sum property
c) commutative property
d) associative property

q4) what is the value of q makes the statement true?
-(q+14) = -3 + (-14)
a) 17
b) -17
c) -3
d) 3

what value of a makes the statement below true?
-10 + a + (-15) = 50
a) 25
b) -75
c) -25
d) 75

(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)

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