Xy = 6
x + y = 9
     x + y = 9
x - x + y = -x + 9
           y = -x + 9
                                          xy = 6
                                x(-x + 9) = 6
                            x(-x) + x(9) = 6
                                 -x² + 9x = 6
                            -x² + 9x - 6 = 0
              -1(x²) - 1(-9x) - 1(6) = 0
                       -1(x² - 9x + 6) = 0
                                 -1           -1
                             x² - 9x + 6 = 0
                             x = -(-9) ± √((-9)² - 4(1)(6))
                                                 2(1) 
                             x = 9 ± √(81 - 24)
                                            2
                             x = 9 ± √(57)
                                        2
                             x = 4.5 ± 0.5√(57)
                       x + y = 9
   4.5 ± 0.5√(57) + y = 9
- (4.5 ± 0.5√(57))    - (4.5 ± 0.5√(57))
                             y = 4.5 ± 0.5√(57)
                       (x, y) = (4.5 ± 0.5√(57), 4.5 ± 0.5√(57))
The two numbers that multiply to 6 and add up to 9 are 4.5 ± 0.5√(57).
        
             
        
        
        
The associative property of addition is shown in equations where the order in which the evaluation is made does not change the result, providing the numbers remain in the same order.  Option B demonstrates this.

Answer:
211.7 Per Day 8.8 Per Hour
Step-by-step explanation:
First you do 1482/7 which gives you an average for each day (211.7)
Then you take 211.7  and divide that by 24 because there are 24 hours in a day and doing so would give you 8.8
