Answer:
3.
Devan scored 7. from the given information, we know that a +ve score means the amount by which the player failed to beat the record
Let the record be x m
Hence, the distance Devan threw = record - 7
Devan's distance = x - 7 m
Similarly, we can see that Joel's score is 15 less than the record
Hence, the distance covered by Joel's discus = record - 15
Joel's Distance = x - 15 m
We are told that the distance covered by Greg's discus is the opposite of Devan
That means that since devan scored 7 , Greg scored the opposite of 7 i.e:
-7
We have been told that a negative score denotes the distance covered by the discus after breaking the record
Hence, the distance covered by Greg's discuss = record + 7
Greg's Distance = x + 7 m
a) Difference between Greg's and Joel's distances
Greg's Distance - Joel's Distance
<em>(x + 7) - (x - 15)</em>
<em>x + 7 - x + 15 = </em><u>22 m</u>
<u></u>
b) Leo's score was 4 less than Greg's Score:
Hence, Leo's score = Greg's score - 4
Leo's Score = (x + 7) - 4
Leo's score = x + 3
Here, we can see that Leo broke the record by 3 points
c) Ordering the scores in Descending order:
We know that Greg has the highest score and Leo is lacking by a few points, then comes Devan and Joel has the least score
(x + 7) > (x + 3) > (x -7) > (x - 15)
4. We know that any non-zero score is the deviation from the record score.
When the scores are given as integers, the absolute value of the score will tell us the deviation from the record score
