Answer:
= 0.38 m/s
Step-by-step explanation:
▪Total distance = 800 m
5 min = 100 m
▪Remaining distance = 800 - 100 = 700 m
20 min = 700 m
▪Total time taken = 20 + 10 + 5 = 35 min
If 1 min = 60 sec
What about 35 min = ? 
= 35 x 60 
= 2100 sec
▪Average speed = TD ÷ TT
= 800 ÷ 2100
= 0.38 m/s
 
        
             
        
        
        
1] y - 3x = -8
  [2] y + 9x = 4
 -3x + y = -8 9x + y = 4 
Solve equation [2] for the variable y 
 [2] y = -9x + 4
// Plug this in for variable y in equation [1]
 [1] (-9x+4) - 3x = -8
 [1] - 12x = -12
// Solve equation [1] for the variable x 
 [1] 12x = 12 
 [1] x = 1 
// By now we know this much :
 y = -9x+4
 x = 1
// Use the x value to solve for y 
 y = -9(1)+4 = -5 
 {y,x} = {-5,1} 
        
             
        
        
        
Answer:
54,706 > 45,802
Step-by-step explanation:
Well, as you know, the > symbol means that one number has a greater value than another. For example, 2 > 1. The way we can find that out is using subtraction. Take 54,706 - 45,802, and if that number is positive, then the first number is greater than the other. 
54,706 - 45,802 = 8,904
8,904 is a positive.
Therefore, 54,706 > 45,802.
