73.
18 = 3x
(divide both sides by 3 )
6 = x ( multiply both sides by )
6 = 3x [ × = 3 ]
divide both sides by 3
x = 2
74.
24 = 2x
( divide both sides by 2 )
12 = x ( multiply both sides by )
12 = 2x ( divide both sides by 2 )
x = 6
75.
9 × x = 18 ( divide both sides by 9 )
x = 2
76.
2 = x × 
( multiply both sides by )
2 = 4x ( divide both sides by 4 )
x = 
Answer:
The speed of the periodic wave is 3 meters per second.
Step-by-step explanation:
Given that:
Wavelength of the periodic wave = 1 m
Frequency of the periodic wave = 3 Hz
We have to find the speed of the wave.
Speed of wave = Wavelength * Frequency of wave
Speed = fλ
Speed = 1*3
Speed = 3 m/s
Hence,
The speed of the periodic wave is 3 meters per second.
