Frequency=(speed of sound)/(wavelength)
that means
wavelength =(speed of sound )/(frequency)
speed of sound=344 m/s
4.
frequency=587. 33 Hz
thus
wavelength=344/587.33
=0.586 m
5.
frequency=493.88 nHz
thus
wavelength=344/493.88
=0.69653 m
6. Frequency= 698.46 Hz
wavelength= 344/698.46
wavelength=0.4925 m
9. Frequency =783.99 Hz
wavelength=344/783.99
wavelength=0.439 m
For this problem you'll get a number, find it's opposite and sum 96 to it. The equation used will be:
x = -x + 96
Where:
x = a number
-x = the opposite of x
So:
x = -x + 96
x + x = 96
2x = 96
x = 96 / 2
x = 48
And now, if you do the sum to prove your answer:
48 - 96 = -48

Answer:
A, 8
Step-by-step explanation:
Use the equation 15+4x=47
Subtract 15 from both sides to get
4x=32
divide to get 8
x=8
