Answer:
missing side = 50
Step-by-step explanation:
using Pythagoras theorem,
30² + 40² = (missing side)²
900 + 1600 = (missing side)²
(missing side)² = 2500
missing side = √2500
missing side = 50
 
        
                    
             
        
        
        
Answer: 150 + 10x =270
Step-by-step explanation:
So basically she makes $150 per week automatically so u can write that. Then, she makes 10 dollars for each pocketbook she sells so that times x since we don’t know how many pocket books. 
If u were to actually have to write how many pocket books you would do 270-150= 120. Then, 120/10= 12 pocketbooks.
 
        
                    
             
        
        
        
Y = -4x/5 + 13/5 would be the answer to 4x+5y=13
