In a game, you will score 20 points if you win but will have 5 points deducted if you lose. Ken played 35 games and scored 475 points. How many games did he win?

X   = 26

Step-by-step explanation:

475 = 20X + (-5) x (35-X)

475 = 20X - 175 +5X

650 = 25X

 X   = 26

*26x20=520-5x9=475

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.
