9(n+7) = 18(n+1)
9n + 63 = 18n + 18
9n = 45
  n = 5
answer
n = 5
        
             
        
        
        
Cost =16000
rate of depreciation = 35%
written down value = 2000
depreciation for one year =16000*35% = 5600
5600*2 = 11200+5600*6\12 = 2000
the car is 2.5 years old. It has been depreciated for 2 whole years and half
years.
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Two points are (0, 65) and (10, 55)
Calculate slope <em>m</em>


Use slope-intercept form


<em>b</em>  is the y-intercept, y-intercept is (0,65)

 
        
             
        
        
        
Answer:
20 times 
Step-by-step explanation:
Given the following :
Probability of rolling a number less than 3 on a number cube:
Required outcome = (1, 2)
Total possible outcomes = (1, 2, 3, 4, 5, 6) 
Required outcome / Total possible outcomes 
= 2 /6
= 1/3
Hence, if number cube is rolled 60 times, number of times a number less than 3 is expected :
(Probability of obtaining a number less than 3 in one roll × number of rolls) 
= (1 / 3) × 60
= 60 / 3 
= 20 times
