Please help with math ASAP, will give brainliest

8 : supplementary, 9 : complementary 10 : neither? (i think that 11 could be 24.66666 but Im not sure)

Step-by-step explanation:

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

the answer is c)8
