Answer:
696
Step-by-step explanation:

First I would multiply each side by 8 to find what M is (because if you multiple m/8 by 8 the 8s will cancel out).

Because any number divided by 1 would just be itself, 696/1 is just 696.
I used the person can see 49km which is my V
SO 49 = 3.5 sqrt (h)
or 49/3.5 = sqrt(h)
or sqrt(h) = 14
or h= 196
So the height is 196
Answer:
1. -4x < 8
2. 4x < 8
3. When something is done to one side of the equation, the same thing must be done to the other side. Dividing each side by -4 in part A would cause the sign to flip because the sign is always flipped when dividing by a negative. Because 4 in 4x (part B) is not negative, the sign is not flipped.

Answer:
The equation has zero solutions because the equation 2 = 3 is never true.
