Step-by-step explanation: (Statement) The reason I know these triangles are similar is because I flipped one up and realized they matched just opposite each other. Then I matched them up they were exactly the same
 
        
             
        
        
        
Answer:
 r= 7.14 (rounded to 2 decimal places)
Step-by-step explanation:
We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.
Distributive property is  a(b+c) = ab + ac
Now, the steps of solving are shown below:

Hence, value of r is 7.14 (rounded to 2 decimal places)
 
        
             
        
        
        
Hola User______
Here is Your Answer...!!!!
_________________
thus the given equation is a linear equation in two variables ...
thus ploting a table we get as ...
y = -5x + 3 
there fore 
1) at y=0 , x = 3/5 .... 0 = -5x +3 
= -5x = -3 ..thus X = 3/5 
2) at x=0 , y= 3 ...
y = -5 (0) + 3 = 3 
3) at X =1 , y = -2 
4) at y=1 , x = 2/5
 
        
             
        
        
        
Answer:2n + 8 = n-3
Step-by-step explanation:
 
        
             
        
        
        
Eliminate parentheses using the distributive property.
  4806x -3204 +2 = 1360 -544x +90x
  5260x = 4562
  x = 4562/5260
  x = 2281/2630
