Answer:
The expression that belongs in the box is 8 x 4
Option C is correct answer.
Step-by-step explanation:
We need to find Which expression belongs in the box?
The property applied here is associative property of multiplication.
Associative property of multiplication states that:
So, if we apply the property to our question we have:
a = 3
b = 8
c = 4
So, the expression will become: 
So, the expression that belongs in the box is 8 x 4
Option C is correct answer.

Answer:
z = 92
x = 11
Step-by-step explanation:
From the figure,
13x - 55 = 88 (Opposite angles made by two straight lines are equal)
13x = 88 + 55
13x = 143
x = 143/13
x = 11
Again,
88 + z = 180 (Sum of angles of a straight line)
z = 180 - 88
z = 92

Answer:
<em>Thus, the original price of the pair of shoes was $100.</em>
Step-by-step explanation:
<u>Percentages</u>
After a 60% discount, the sale price is now valued at 100-60=40% of its original price.
If the sale price is $40, then the original price is calculated as
$40 / 40 * 100 = $100
Thus, the original price of the pair of shoes was $100.
Verify applying 60% discount:
$100 - 60*$100/100 = $40
