Consider the steps to simplify the expression. which property is used to reach step 3? expression: -4 3 7 + 7 + (-3 4 7 ) step 1: = -4 3 7 + (-3 4 7 ) + 7 step 2: = -4 + (- 3 7 ) + (-3) + (- 4 7 ) + 7 step 3: = -4 + (- 3 7 ) + (- 4 7 ) + (-3) + 7 step 4: = -4 + (-1) + (-3) + 7 step 5: = -8 + 7 step 6: = -1 a) the associate property of addition. b) the commutative property of addition. c) the opposite of a sum is the sum of its opposites. d) subtracting a number is the same as adding its inverse.

NOTE: I ACCIDENTALLY clicked one star. That DOES NOT count as a real rating, and this DOES NOT mean my answer is bad!

Commutative Property of Addition

Step-by-step explanation:

Step 2: -4 + (-37) + (-3) + (-47) + 7

Step 3: -4 + (-37) + (-47) + (-3) + 7

Because the order was changed, it is the Commutative Property.

c is the answer

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
