Answer: $1,350
Step-by-step explanation:
45 hours x 10 dollars/hour = 45x10 dollars = 450 dollars/week
450 dollars/week x 3 weeks = 450x3 dollars = 1350 dollars
 
        
             
        
        
        
We can solve for x by raising both sides to the -3 power (which is the reciprocal of -1/3):
(c^-1/3)^-3 = x^-3
c^1=x^-3
c=x^-3
Since the exponent on the x is a negative, we have to move it to the denominator to make it positive:
c= 1/x³
        
                    
             
        
        
        
Answer:
x = 6
Step-by-step explanation:
3(x - 4) = 12 - 2(x - 3) 
3x - 12 = 12 - 2x + 6
3x - 12 = 18 - 2x
+2x              + 2x
5x -12 = 18 
    + 12   +12
5x = 30
x = 6
