Answer:
to make a unit rate using a table you would take an input/output from a table and convert it into a fraction. Then you would take that fraction and simplify it. Sometimes you might have to choose a new input/output in order to make the simplification easier.
Example-
2:4
4:8
6:12
8:16
         Turn one into a fraction
4/8
        Simplify
1/2
 
        
             
        
        
        
The number that was left out is 70. 
<h3>What is the number that was left out?</h3>
Average is the sum of a set of numbers divided by the total numbers in the data set. 
Average = sum of numbers / total numbers
- Sum of numbers when there are 8 numbers = 56 x 8 = 448
- Sum of numbers when there are 7 numbers = 54 x 7 = 378
- Difference = 448 - 378 = 70

Step-by-step explanation:
I can see it in the demonstration graph
 
        
                    
             
        
        
        
multiply the hourly rate by number of hours worked
12.75 x 35.25 = 449.44 per week
449.44 x 2 = 898.88 for two weeks
 
        
                    
             
        
        
        
Answer:
See below in bold.
Step-by-step explanation:
You work in fractions of the city streets done per hour:
1/200 + 1/400 = 1 /x  where x is the number of hours taken by 2 teams.
Multiply through by the LCM 400x:
2x + x = 400
3x = 400
x =  133.33 hours.
As there are 168 hours in a week they will have enough time.
