Answer:
3x+85= 21
or, 3x= 85- 21
or, 3x= 64
or,x= 64/3
;. x= 21.3
Step-by-step explanation:
the value of x is 21.3
 
        
             
        
        
        
Answer:
 
 
Step-by-step explanation:
we know that                              
In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, and this constant is called the common difference (d)
In this problem we have the ordered pairs
 
                      
Let                                          

Find the difference between one term and the next
 
               
 
                  
 
                         
 
                              
 
                                                         
The difference between one term and the next is a constant         
This constant is the common difference                   
so                                                                                                                                   
The sequence graphed is an Arithmetic Sequence                    
therefore                                                                                    
The first term is  
                                     
The common difference is equal to

The area of the top of the table is 28 × 20 = 560 cm2. The area of Patty’s tiles is 8 cm2 each and the area of Jake’s tiles is 9 cm2 each. Patty will need 560 ÷ 8, or 70, tiles. Jake will need 560 ÷ 9, or about 63, tiles. So, Patty will use about 7 more tiles.
