Hey do you have a question you have to read
Answer:
n = 2
Step-by-step explanation:
Given
(n - 4) - 3 = 3 - (2n + 3)
Multiply through by 2 to clear the fraction
n - 4 - 6 = 6 - 2(2n + 3) ← distribute
n - 10 = 6 - 4n - 6 ( add 4n to both sides )
5n - 10 = 0 ( add 10 to both sides )
5n = 10 ( divide both sides by 5 )
n = 2
22% of those surveyed liked neither pop nor rap music.
Step-by-step explanation:
It is given that,
The 11th grade class at Red Hook high school was surveyed about the types of music they liked.
- Pop music ⇒ 64%
- Rap music ⇒ 52%
- Both pop and rap music ⇒ 38%
We know that, the total survey is 100%.
<u>To find the percent of those surveyed liked neither of the music :</u>
Let x be the percentage of those liked neither pop or rap music.
The formula used here is ,
Total = Pop + rap - Both + neither.
⇒ 100% = 64% + 52% - 38% + x
⇒ 100% = 78% + x
⇒ 100% - 78% = x
⇒ x = 22%
Therefore, 22% of those surveyed liked neither pop nor rap music.
