No, they are not equivalent.
5(2x - y) = 10x - 5y and it is not equal to 15x - 5y.

Answer: 4%-16000 and 9.5%-30000
Why:
1) x+y=46000
x=46000-y
2) 4%x+9,5%y=3490;
4x + 9.5y=349000; so 4*(46000-y)+9.5y=349000;
5.5y=165000
y=30000
x=46000-30000=16000
 
        
             
        
        
        
It depends on the function
        
                    
             
        
        
        
well... 42+24=66 so the height of the attic is 66 feet
 
        
             
        
        
        
Answer:
x < 8
Step-by-step explanation:
Given
x + 4 < 12
Isolate x on the left side by subtracting 4 from both sides
x < 8 ← is the solution
