7. There are 4 times as many boys
as girls in a class with 28 boys. How
many girls are there?

There are 7 girls

Step-by-step explanation:

28 divided by 4 equals 7

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

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.
