Answer:
5x-18=4x+7 ( vertical opposite angle)
5x-4x=7+18
x=25
Given:
Consider the given equation is
To find:
The values of x.
Solution:
We have,
Taking square root on both sides, we get
Adding 18 on both sides, we get
Now,
and 
and 
Therefore, the correct option is A.
Solve for w and l by using the system of equations.
2l=-2w+228
l=w+42
Substitute w+42 for l in the first equation.
2(w+42)=-2w+228
2w+84=-2w+228
4w=144
w=36
Now substitute 36 for w in any equation to get l=78.
To graph the equations, first make them equal l.
l=-w+114 and l=w+42 are your equations. You ca plug in values for w to plot points on the graph.
For this equation, all you need to do is plug in the numbers to the equation...
(3/2)6 - 3 + (5/3)3
Then you simplify...
(18/2) - 3 + (15/3)
Then divide...
9 - 3 +5
Then subtract and add...
9-3=6
6+5=11
Answer: 11
