Alrighty, what I was always taught was to start by writing out what you know from the question.
What I know:
-Tom is paid $0.23 for every page of proofs.
-He proofreads 1,992 pages.
In order to figure out how much money Tom has made, we need to multiply 0.23 by 1,992. Multiplying allows us to see the total amount of money made by proofreading x amount of pages - for every page he proofreads, he makes $0.23.
0.23×1992=458.16
Therefore, Tom made $458.16.
Hope this helps!
        
             
        
        
        
Let x = the total number of pennies her piggy bank can hold.
Then 2/3x = the number of pennies she started with
Then 2/3x - 80 = the number of pennies she has left after taking out 80 pennies.
Then 1/2x = the number of pennies she has left after taking out 80 pennies.
Build the equation.
2/3x - 80 = 1/2x
Subtract 1/2x from each side of the equation.
(2/3x - 80) - 1/2x = 1/2x - 1/2x
1/6x - 80 = 0
Add 80 to both sides of the equation.
(1/6x - 80) + 80 = 0 + 80
1/6x = 80
Divide both sides by 1/6.
(1/6x) / 1/6 = 80 / 1/6
x = 480
So, Linda's piggy bank can hold 480 pennies!
        
             
        
        
        
 Answer:
 x = 5 or x = 1
Step-by-step explanation:
Absolute Value Equation entered :
      3|3x-9|=18 
Step by step solution :
Step 1: Rearrange this Absolute Value Equation
Absolute value equalitiy entered
      3|3x-9| = 18 
Step 2: Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is 3|3x-9|
 For the Negative case we'll use -3(3x-9) 
For the Positive case we'll use 3(3x-9) 
Step 3: Solve the Negative Case
      -3(3x-9) = 18 
Multiply
      -9x+27 = 18 
     Rearrange and Add up
      -9x = -9 
     Divide both sides by 9
      -x = -1 
     Multiply both sides by (-1)
      x = 1 
     Which is the solution for the Negative Case
Step 4: Solve the Positive Case
(3x-9) = 18 
     Multiply
      9x-27 = 18 
     Rearrange and Add up
      9x = 45 
     Divide both sides by 9
      x = 5 
     Which is the solution for the Positive Case
Step 5:  Wrap up the solution
 x=1
 x=5
