R^4-2(r-14)>0
r^4-2r+28>0
r^4-2r+28=0
There is no real solution but there is all real numbers

True, you would use the ratio of minutes to seconds.
        
             
        
        
        
He would have to work 24 weeks to get the same amount from each job.
 
        
             
        
        
        
4(0.5n-3)=n-0.25(12-8n)
2n-12=n-3+2n
2n-12=3n-3
2n-3n=-3+12
-n=9
n = -9
        
             
        
        
        
Use distributive method
5r - 50 = -51
Add 50
5r = -1
Divide by 5
r = -1/5
