At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music. If 210 sixth-grade students prefer hip hop music, how many sixth-grade students are at the school?

350 6th grade students

Step-by-step explanation:

From the question

At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music.

Total number of sixth graders that love hip-hop = 210

Let the total number of students in the school be represented as: x

Hence,

60% × x = 210

60/100 × x = 210

Cross Multiply

60x = 210 × 100

x = 210× 100/60

x = 350 students.

Therefore, the total number of sixth graders is 350 .

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
