The can of green beans that has the lowest unit price is the 8 oz. size.
To find the unit price of each size, divide the cost by the size. (A number below that's in parentheses means it goes on forever)
0.89 ÷ 6 = 0.148(3)
1.04 ÷ 8 = 0.13
1.69 ÷ 10 = 0.169
4.79 ÷ 32 = 1496875
Among all of these answers, the can with 8 oz. has the least unit price/rate. Thus, this is the answer. 
        
             
        
        
        
Step-by-step explanation:
16+10+4
26+4

30÷(2+2)
30÷4
7 1/2
 
        
             
        
        
        
In this case, 7 is being added to the odometer which already reads 78. If you add 7 to 78, you get 85. Meaning y = 85! 
 
        
                    
             
        
        
        
Answer:
x = -2 y = -8
Step-by-step explanation:
13x - 6y = 22
x - y = 6
6(x-y) = 6*6
6x - 6y = 36
subtract both the equations
13x - 6x -6y + 6y = -14
7x = -14
x = -2
13*-2 -6y=22
-26 -6y=22
-6y = 48
y = -8
answer: x = -2  y = -8
