Answer:
31m/s
Step-by-step explanation:
Using the equation of motion
v² = u² + 2gH
H is the height of fall = 49m
g is the acceleration due to gravity = 9.8m/s²
u is the initial velocity = 0m/s
v² = 0² + 2(9.8)(49)
v² = 960.4
v = √960.4
v = 30.9m/s
v ≈ 31m/s
Hence the velocity of water at the turbine is 31m/s
The -3 and 2 are just the numbers you multiply by to get the variable 's' have opposite values in the 2 equations so that when you add the 2 equations, they would cancel out

Answer:
The value of x in this equation is 8.
Step-by-step explanation:
5x - 1 = 6x - 9
Subtract 6x on both sides.
-x - 1 = -9
Add 1 to both sides.
-x = -8
Divide by -1 on both sides.
x = 8
