I need help please, please help me it done tomorrow

Step-by-step explanation:

6). 8 - x ≥ 3 ; x = 2

8 - 2 ≥ 3

6 ≥ 3 ( true) ⇒ Yes, x = 2 is the solution.

7). 15 ≤ 4w ; w = 3

15 ≤ 4(3)

15 ≤ 12 (false) ⇒ NO, w = 3 is not a solution.

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:
