Answer:
30.25 in decimal form
30 1/4 in fraction form
Step-by-step explanation:
12(3) − 3(1/3) / 4(3)− (5)  = 30.25 or 30 1/4  
 
        
                    
             
        
        
        
The answer is no, because the first two equations are right but the third equation equals -16 instead of -15. So the answer is no (2,-2,4) is not the solution to all the system of equations.
        
             
        
        
        
Answer:
The solution region is x < –5 and x > 2
Step-by-step explanation:
We are given the inequalities, 2x–2 < –12 or 2x+3 > 7
Upon simplifying the inequalities, we get,
A. 
 i.e.
 i.e.  i.e.
 i.e. 
B.  
  i.e.
 i.e.  i.e.
 i.e. 
So, we get the solution is  or
 or  and the plotted region can be seen below.
