Answer: 51 notes span 6 octaves.
Step-by-step explanation:
The word "octave" is a Latin word that means "eight".
In an instrument, Each octave is made up of 8 musical notes.
If we have 51 notes , the number of octaves can be made in it = ![\dfrac{51}{8}](https://tex.z-dn.net/?f=%5Cdfrac%7B51%7D%7B8%7D)
![=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}](https://tex.z-dn.net/?f=%3D6.375%5Capprox6%5C%20%5C%20%5C%20%5C%20%5C%20%5Ctext%7B%5BRounded%20to%20the%20nearest%20whole%20number%5D%7D)
Hence, 51 notes span 6 octaves.
Answer:x=2 and y=3
Step-by-step explanation:
Given that y=2x-1

3x+4x-2=12
7x=14
x=2
y=2(2)-1
y=3
