Q:
# Write an expression that is equivalent to −30+(−40)+(−70) using the commutative property of addition.HINT: Your answer should be in this form: X + Y + Z NOT just one number

Accepted Solution

A:

Answer:The desired expression is −30+ (−70) + (−40) or −70 + (−40) + (−30)Step-by-step explanation:Here, the given expression is −30+(−40)+(−70) Let us assume here, X = (-30)Y = (-40) and Z = (-70)So, the given expressions is of the form X + Y + ZCommutative Property states that for any number A, B and C:A+ (B+C) = (A+B) + CSo, here ( X+Y) + Z = X+ (Y +Z)⇒The given expression can also be written as −30+ (−70) + (−40), or, −70 + (−40) + (−30)Hence, the desired expression is −30+ (−70) + (−40), or, −70 + (−40) + (−30)
