Hi!
We know that there are three measures and each has a different amount of notes. To find the total we add them all up.
8+16+4=28.
There were 28 total notes played in the song.
I hope I helped you!
Have a wonderful day!
Answer:
y is also doubled.
Step-by-step explanation:
Direct proportionality between
and
means that
![y \propto x](https://tex.z-dn.net/?f=y%20%5Cpropto%20x)
or
,
which indicates a linear relationship between
and
because they are related by a constant.
Therefore, if x is doubled, then the new value of
is ![y_{new}](https://tex.z-dn.net/?f=y_%7Bnew%7D)
![y_{new}=c(2x)](https://tex.z-dn.net/?f=y_%7Bnew%7D%3Dc%282x%29)
![y_{new}=2(cx)](https://tex.z-dn.net/?f=y_%7Bnew%7D%3D2%28cx%29)
![y_{new}=2y](https://tex.z-dn.net/?f=y_%7Bnew%7D%3D2y)
The new value of
is 2 times the previous; therefore,
is doubled as
is doubled.
Answer:
x=100
Step-by-step explanation:
39.99+0.45x=44.99+0.4x
