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)
Answer:
I would say 2 because the decimal I came out with was 2.09

Answer:
sales tax = $3.9
total cost = $68.9
Step-by-step explanation:

Answer:
x = 0
Step-by-step explanation:
2(x - 3) + 9 = 3(x + 1) + x
2x - 6 + 9 = 3x + 3 + x
2x + 3 = 4x + 3
2x - 4x = 3 - 3
-2x = 0
2x = 0
x = 0/2
x = 0
