Answer:
infinite solutions
Step-by-step explanation:
Multiply the first equation by 2
2(3x-5y) = 2*15
6x - 10y = 30
This is the same as the second equation
They are the same line
This means there are infinite solutions
 
        
             
        
        
        
Answer:
13 
Step-by-step explanation:
Given: 
- Square stickers that were 3/4 in long 
- The spine is 10 and 1/2 in long 
If she laid the stickers side by side without gaps or overlaps so the number of sticker to cover the length of the spine: 

10 :  ≈13
 ≈13  
She needs 13 stickers cover the length of the spine 
 
        
                    
             
        
        
        
2 pounds  ---- 100%
x pounds -----18%
x=(2*18)/100=36/100=0.36 pounds
