Conditional statement is a statement with a hypotesis and a conclusion:
 
 
or mathematically  .
.
Converse statement of  is statement
 is statement  .
.
If you negate (that means stick a "not" in front of) both the hypothesis and conclusion, you get the inverse:
 .
.
Finally, if you negate everything and flip p and q (taking the inverse of the converse) then you get the contrapositive:
 .
.
Example:
1. Conditional statement: If I am sleeping, then I have closed eyes. (true)
2. Converse statement: If I have closed eyes, then I'm sleeping. (not necessarily true)
3. Inverse statement: If I'm not sleeping, then I haven't closed eyes. (not necessarily true)
4. Contrapositive statement: If I haven't closed eyes, then I'm not sleeping. (true) 
 
        
             
        
        
        
Answer:
2321 ft.
Step-by-step explanation:
When Cai traveled from New Orleans to the Ozark Mountains in Arkansas the elevation changes from 7 ft below sea level to 2314 ft above sea level.
If we consider the elevation below sea level as negative and the elevation above sea level as positive, then the elevation changes from - 7ft to +2314 ft. 
Therefore, the increment of elevation is by [2314 - (- 7)] = 2321 ft. (Answer)
 
        
             
        
        
        
1 = x + 4 
3 = x
2 = 2x + 5
3 = 2x
3/2= x
