Given
You created a new playlist in 100 of your friends listened to it and shared if they liked
The new playlist said the ratio Of people who liked the playlist to those who did not like the playlist is 75:25.
Dylan said that for every three people who like to playlist one person did not
Find out Do Nadhii and Dylan Agree or not.
To proof
As given in the question
created a new playlist in 100 of your friends listened to it and shared if they liked
new playlist said the ratio Of people who liked the playlist to those who did not like the playlist is 75:25.
Simply the ratio of people who liked the playlist to those who did not like the playlist

Thus

also
Dylan said that for every three people who like to playlist one person did not
In the form of ratio written as

the value of both new playlist and Dylan said about the ratio of people who liked the playlist to those who did not like the playlist is 3:1.
The value both of their ratio are equivalent .
Thus Nadhii and Dylan Agree
Hence proved
The substitution method means you replace the variable in one equation with the other equation, so your new equation is x+4x-8=10. Add 10 to both sides to get 5x=18. Divide both sides by 5 to get x=3.6. This is a weird equation, but then to get y, work backwords. 3.6 times 2=7.2. 7.2-4=3.2 y=3.2. Finally to finish checking solve the equation as normal. 3.6+6.4=10. I hope this helped! Please give brainliest!
Your final answer is x=3.6 y=3.2
Using the <em>system of equation</em> created, Emily will catch up Lucy after 30 seconds
Given the Parameters :
- Lucy's distance = 2t
- Emily's distance = 5t
<u>We can set up an equation to represent the required scenario thus</u> :
Emily's distance = Lucy's distance + 90
5t = 2t + 90
We solve for t
<em>Collect like terms</em> :
5t - 2t = 90
3t = 90
Divide both sides by 3 to isolate t
t = 90/3
t = 30
Therefore, Emily will catch up with Lucy after 30 seconds
