Answer:
Step-by-step explanation:
add 14.52 to both sides of the inequality to cancel that value out from the middle. Then you can divide both sides by 3x to get x by itself in the middle.

- (2nd picture): y=4x+2 and y =3x+2
- (3rd picture): y=2x+1 and y =x+2
- (4th picture): 3x and x+3
<h3>What does the graph of an equation shows?</h3>
The graph of the linear equation is known to be one that often brings or  set the  points that can be found on the coordinate plane and it is one that shows all the solutions to the equation. 
Note that when  all variables stands for real numbers, a person can be able to use graph to show the equation and this is often done through plotting the points to show a pattern and then link up the points to have all the points.
From the above, the pictures that have all the points as shown on the graph are:
- (1st picture): y=2x+3 and y=x+5
- (2nd picture): y=4x+2 and y =3x+2
- (3rd picture): y=2x+1 and y =x+2
- (4th picture): 3x and x+3

Answer:
21 is 20% of 105
Step-by-step explanation:
20% * x = 21 
20/100 * x = 21 
x = 21 * 100/20 
x = 105
If you are using a calculator, simply enter 21×100÷20, which will give you the answer.
