Answer:
Alberta's total overtime pay of the week was $ 145.80.
Step-by-step explanation:
Given that Alberta worked 6 hours at time-and-a-half pay, and 3 hours at double-time pay, and that the value of her regular work hour is $ 9.72, to determine the value of the pay of his overtime, the following equation must be performed:
6x1.5x9.72 + 3x2x9.72 = X
9x9.72 + 6x9.72 = X
87.48 + 58.32 = X
145.8 = X
Therefore, Alberta's total overtime pay of the week was $ 145.80.

Answer:
The given equation is NOT justified.
Step-by-step explanation:
Here, the given equation is  =
   = 
Now, here Consider the left hand side and simplifying the left side by operating on the like terms, 
⇒ =
   = 
=
Here, Left side of equation  ≠ Right side of the equation 
Hence,  ≠
   ≠ 
 
        
             
        
        
        
Answer:
13) x=n-11
15) x=3*10
Step-by-step explanation:
I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!
