Ok i tried and ig youre looking for what a and b equal for both systems..... it'll be 1) a=-2b+15 b=7.5-(1/2)a <-- fraction........2) a=-6+b b=6-a
        
             
        
        
        
Only Table 2 shows direct variation.  Every y value is 7 times the associated x value.
        
             
        
        
        
Answer:
3x 
Step-by-step explanation:
 9x^2 ?6x 
9x? 6x
÷3x. ÷3x
=3x and 2x 
highest number is 3x 
 
        
             
        
        
        
We could use the Pythagorean theorem for this kind of problem I think:
A^2 + B^2 = C^2
6^2 + 16^2 = C^2
36 + 256 = C^2
292 = C^2
17.08 = C
C = 17.1 to the nearest tenth 
Sorry if it’s wrong and glad I could help if it’s right ❤️❤️ Take care!
        
             
        
        
        
30 & 150. 150 is five times 30, and 150+30=180
