Answer:
The answer to your question is:
x = 1
y = 1
z = 0
Step-by-step explanation:
                                 -2x + 2y + 3z = 0             (1)
                                 -2x - y + z = -3                  (2)
                                  2x + 3y + 3z = 5              (3)
Solve (1) and (2)   
Multiply 2 by 2
                                  -2x + 2y + 3z = 0
                                  -4x -2y   + 2z = -6
                                 -6x          + 5 z = -6        (4)
Solve (2) and (3)
Multiply 2 by 3
                                -6x - 3y + 3z = -9
                                 2x + 3y + 3z = 5
                                -4x         + 6z = -4           (5)
Solve (4) and (5)
Multiply (4) by 2 and (5) by -3
                            -12x    + 10 z = -12
                             12x    -  18z   = 12
                                          -6z = 0
                                           z = 0
Then 
             -4x + 6(0) = -4
            -4x = -4
             x = -4/-4
             x = 1
 
Finally
                  -2(1) - y + (0) = -3       
                 -2 - y = -3
                  -y = -3 + 2
                  y = 1  
    
 
        
                    
             
        
        
        
Answer:
16.67
Step-by-step explanation:
30: 180÷100 =
( 30÷00): 180 =
3000: 180 = 16.67
 
        
             
        
        
        
The answer is 33 
3(-2)^2+4(-2)+5
-6^2+ (-8) + 5
36 + (-8) + 5
28+5
33
