Answer:
14%
Step-by-step explanation:
A way I usually do it is with a fraction setup.
280/2000 = ?/100
multiply 280 by 100, and you get 28000. divide this by 2000, and you get 14!
 
        
             
        
        
        
Given equation : n(17+x)=34x−r.
We need to solve it for x.
Distributing n over (17+x) on left side, we get 
17n + nx  = 34x - r.
Adding r on both sides, we get 
17n+r + nx  = 34x - r+r.
17n + r + nx = 34x.
Subtracting nx from both sides, we get 
17n + r + nx-nx = 34x-nx
17n + r = 34x -nx.
Factoring out gcf x on right side, we get 
17x + r = x(34-n).
Dividing both sides by (34-n), we get 


<h3>Therefore, final answer is

Each time they assume the sum<span> is </span>rational<span>; however, upon rearranging the terms of their equation, they get a contradiction (that an </span>irrational number<span> is equal to a </span>rational number<span>). Since the assumption that the </span>sum of a rational<span> and </span>irrational number<span> is </span>rational<span>leads to a contradiction, the </span>sum<span> must be </span>irrational<span>.</span>

Step-by-step explanation:
Polygon WXYZ has vertices W(-1.5, 1.5), X(6, 1.5), Y(6, -4.5), and Z(-1.5, -4.5).
Find the slopes of all sides:
 - horizontal line
 - horizontal line
 - slope undefined, so the line is vertical
 - slope undefined, so the line is vertical
 - horizontal line
 - horizontal line
 - slope undefined, so the line is vertical
 - slope undefined, so the line is vertical
Vertical and horizontal lines are perpendicular, so all angles W, X, Y and Z are right angles. Hence, quadrilateral WXYZ is a rectangle
