Answer:
10 m / minute
Step-by-step explanation:
Starting position = North ; back to North gives a Displacement of 0 ; the from that position to 900 m south gives a final Displacement of 900
Displacement / time
Displacement = 900
Time = 9 minutes
900 / 9
= 10 m / minute
Answer:
x = (-629)/4
Step-by-step explanation:
Solve for x:
-2 x - 18 = 4 x - 2 x + 611
4 x - 2 x = 2 x:
-2 x - 18 = 2 x + 611
Subtract 2 x from both sides:
(-2 x - 2 x) - 18 = (2 x - 2 x) + 611
-2 x - 2 x = -4 x:
-4 x - 18 = (2 x - 2 x) + 611
2 x - 2 x = 0:
-4 x - 18 = 611
Add 18 to both sides:
(18 - 18) - 4 x = 18 + 611
18 - 18 = 0:
-4 x = 611 + 18
611 + 18 = 629:
-4 x = 629
Divide both sides of -4 x = 629 by -4:
(-4 x)/(-4) = 629/(-4)
(-4)/(-4) = 1:
x = 629/(-4)
Multiply numerator and denominator of 629/(-4) by -1:
Answer: x = (-629)/4
