54 first-graders and 546 other students attended a school assembly. What percentage of the students at the assembly were first-graders?

9 percent

Step-by-step explanation:

the total students were 600. 5r were first graders. they were both divisible by 6 so i simplified it into 9 first graders for 100 total students. this is then turned into a percentage which was 9 percent.

does this deserve a brainliest ?

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
