Answer:
thats too long to read but good luck!
Step-by-step explanation:
<span>going downstream -
t = 14/(2 + v)
going upstream -
t = 7/(2 - v)
14/(2 + v) = 7/(2 - v)
(2 + v)/2 = 2 - v
v = 2/3km/h</span><span>

Answer:
This is a reflection in the axis or line through AB.
Step-by-step explanation:
Since a triangle is well defined other than its handedness by the length of two sides with the angle between those two sides, and noting the diagram shows that the sides and angle sandwiched are equal but for the fact that the order is reversed, so this is a reflection in the axis or line through AB.
10 feet 6 inches = 126 inches. Length of the car is 126 inches and the model length is 7 inches.
126 : 7 = 18
The scale factor of the model to the actual car is 1 : 18.
7(x+4)>0
Distribute 7. (multiply by x and 4)
7x+28>0
Subtract 28 on both sides.
7x>-28
Divide by 7 into both sides.
x>-4
x>-4 is the answer.
I hope this helps!
