Answer:
Lionel had copied 250 pages
Step-by-step explanation:
Given that the local office supply store charges $0.08 per page to make photocopies and Lionel paid $20.00 for a set of copies. Then, the following proportion must be satisfied:
$0.08/$20 = 1 copy/x copies
Solving for x:
x = 1*20/0.08 = 250 copies
x=5
Step 1: Subtract 3x from both sides.
6x−3−3x=3x+12−3x
3x−3=12
Step 2: Add 3 to both sides.
3x−3+3=12+3
3x=15
Step 3: Divide both sides by 3.
3x/3=15
-3(2x+1) > -2(x+6)
-6x -3 > -2x - 12
-6x -3+6x > -2x - 12+6x
-3>4x-12
-3+12>4x-12+12
9 > 4x
4x<9
x<4/9
(-∞, 4/9)
