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.

Step-by-step explanation:

Given expression :

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

In 3rd step they just swap the positions of (-4/7) and (-3) to bring the like fractions with common denominator together.

Swapping the numbers is the Commutative Property of Addition.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
