The answer is 1 , because x-2 becomes 2x and you subtract 5x from 2x and and get 3x and 3/3 is 1
        
             
        
        
        
B(x) = 100 - 3.5x
84 = 100 - 3.5x
3.5x = 100 - 84 = 16
x = 16/3.5 = 4.6 kilometers
96 = 100 - 3.5x
3.5x = 100 - 96 = 4
x = 4/3.5 = 1.1 kilometers
Therefore, the boiling point of water is between 84°C and 96°C at elevations of between 4.6 kilometers and 1.1 kilometers.
        
             
        
        
        
Answer: 50% increase
Step-by-step explanation:
Think of 20 as 100%
Half of 20 is 10 which is 50% in this scenario.
30-20=10
This means that the price of the item increased by 50% or 10.
 
        
             
        
        
        
Percent of turn pike is 75% and percent of parkway is 25%.
<u>Solution:</u>
Given, The state of New Jersey makes approximately $1.55 billion annually from tolls of the $1.55 billion
About  comes from tolls on the turnpike
 comes from tolls on the turnpike 
Remaining  comes from tolls on the parkway
 comes from tolls on the parkway  
<em><u>To find the percent of the total revenue from turnpike:</u></em>

<em><u>To find the percent of the total revenue from parkway:</u></em>

<em><u>Summarizing the results:</u></em>
Percent of turn pike is 75% 
Percent of parkway is 25%
