Answer:
40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.
Step-by-step explanation:
Given that:
Hourly rate = d 
Earning to first 40 hours = 40d 
Earning of more than 40 hours = 1.5d 
Amount paid per week = $770 
Hours worked = 50 hours 
first 40 hours + 10 hours = total earned 
40d + 10(1.5d) = 770 
Hence,
40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.
 
        
             
        
        
        
Answer:
The value of x is 14
Step-by-step explanation:
The value of x is 14 because the smaller triangle was dilated by 3 to get the bigger triangle. I figured this out because
9 ÷ 3 = 3
so this would mean that 5 was dilated by 3 also. So to figure this out, it would be
5 × 3 = 15 
1 of that 15 is already there.
So this means that
15-1=14
A=14
I hope this helps you.
 
        
                    
             
        
        
        
(40 min)/(5 mi) = (time)/(7 mi) . . . . . the rates are the same
(7/5)*(40 min) = time = 56 min
At the same rate, it would take Petra 56 minutes to jog 7 miles.
