Answer: 15
Step-by-step explanation:
From the question, we can infer from the information given that:
5 eclaires boxes = 1 free eclaires box.
Therefore, to get the number of eclaires boxes that the kids will get if they bring 77 eclaires boxes, we have to divide 77 by 5 and this will be:
= 77 / 5
= 15.4
= 15
The group of kids will receive 15 free boxes
 
        
             
        
        
        
Answer:
D 1.33
Step-by-step explanation:
B and C are less than 1 
A is one and .30
D is one and .33
33>30
 
        
                    
             
        
        
        
Answer: A or D i think sorry if wrong but a i think
Step-by-step explanation:
but The distance between A and B = |B - A|
We have -12 and -1.
Substitute:
|-1 - (-12)| = |-1 + 12| = |11| = 11
Answer: 11 units
 
        
             
        
        
        
The expressions 100×10 and the more complicated
(100 - 4a)(10 + a)
are calculating annual (expected) revenue.  In 100×10 the 100 is the number of decks and the 10 is the price per deck.  In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck.  So a must be the amount the price increases.
Answer: amount of price increase, last choice
 
        
                    
             
        
        
        
Answer:
The first blank is 81 +9=x-1
+9=x-1
The second blank is 9x+3=x^2-1
Step-by-step explanation:
For the first part, you must set up the equation (9x+3)^2       then you must multiply the exponent to the inside exponents  +
+ next, simplify.
 next, simplify.
81 +9=x-1
+9=x-1
For part two, set up equation.  Then simplify 9x+3=
 Then simplify 9x+3=
