Answer:
x = 25
Step-by-step explanation:
Here's my work. Basically, I knew that the x in angle A is alternate interior to angle C, so they would both be x. the 50 degrees is one a 180 degree line, so the inside of the triangle DCB is 130. X must equal x, so they would both be 25 degrees.
 
        
             
        
        
        
Hey there :)
Before translating the sentence into mathematics, let r represent 'a number'
5 times a number = 5r
2 times that number = 2r
The difference between them = 5r - 2r 
* Your equation 
5r - 2r
* Solving the equation 
= 5r - 2r
= 3r
        
             
        
        
        
(5/3)*(7/3) = 35*(1/3)²
The area is 35 square units.

(a) Kim x years old 
Jordan x+7 years old 
4(x+7)=200
An Equation That Could Be Used To Solve For Kim's Age , x Is 4x+28=200.
(b) 4x=200-28
 4x=172 
 x=43 
Kim Is 43 Years Old.
(c) x+7
 =43+7 
 =50 
Jordan Is 50 Years Old.
