Answer:
x=3
Step-by-step explanation:
1. set the sides equal to each other
8x-12=12
2. solve for x
8x=24
x=3
30u^2v^3 and 8u^5v is : 2u^2v
Answer:
y = (3 × 10^8 m/s)/x
Step-by-step explanation:
Speed of a wave is given by the product of wavelength and frequency.
Thus; speed = frequency × wavelength
If x = wavelength and y = frequency then speed will be;
speed = yx
Thus to get wavelength, y;
y = speed/x , but speed is 3 × 10^8 m/s
Thus;
y = (3 × 10^8 m/s)/x
