Answer:
Step-by-step explanation:
x + y = 7 + 2/8 = 58/8
x - y = 2 + 4/8 = 20/8
Add the equations together
2x = 78/8
x = 39/8 
y = x - 20/8 = 19/8
x = 39/8 = 4⅞
y = 19/8 = 2⅜
 
        
             
        
        
        
Answer:
width is 6 ft, length is 24 ft
Step-by-step explanation:
We can set up 2 equations to help us solve this.  
Equation 1:  "The area is 144 square feet"  gives us 
                  LW = 144  (area of a rectangle)
Equation 2:  "the width is 1\4 of the length" give us 
                  W = L/4             
We can plug the second equation into the first equation...
   Since W = L/4, we get
      L(L/4) = 144      (W becomes L/4)
  
Now solve for L
  L²/4 = 144
  
      L² = 624    (multiply both sides by 4)
         L = 24 ft    (take the square root of each side)
Since L = 24, and W = L/4, 
   W = 24/6,    so W = 6 ft
  
      
 
        
             
        
        
        
Answer:
y = -4/3x - 3
Step-by-step explanation:
 
        
                    
             
        
        
        
N = 9 * 27 + 2 * 31 - 28
n = 243 + 62 - 28
n = 305 - 28
n = 277
Firstly do the multiplications and divisions, then additions and substractions.
Hope I could help :)
