Answer:
4/5 or 0.8
Step-by-step explanation:
1/3x = 5/12
<em>cross</em><em> </em><em>multiply</em>
(12×1) = (5×3x)
<em>divide</em><em> </em><em>through</em> <em>by</em> <em>1</em><em>5</em>
x = 12/15
x = 4/5 <em>o</em><em>r</em><em> </em>0.8
 
        
             
        
        
        
Answer:
7x +2y =24 --------- (i) 
8x +2y= 30 ---------(ii) 
Subtracting eqn. (i) & (ii) 
7x +2y =24
8x +2y= 30 
- - - 
___________
-x = - 6
Putting the value of x in eqn. (i) 
7*6 +2y =24
42 +2y =24
2y =-18
y = - 9
Hence, x=6 and y= - 9
Hope it helps!! 
 
        
             
        
        
        
Step-by-step explanation:
12000 abitanti all'inizio del 2007 
nati: 1.7% × 12000 = 204
morti: 2% × 12000 = 240
popolazione all'inizio del 2008: 12000 + 204 - 240 = 11964
 
        
             
        
        
        
200 because:
250 or higher is 300
249 or lower is 200
