please answer me 10th question with step by step explanation ​

Answer 1

Step-by-step explanation:

10)team A scored= (-20),15,7

now , for the total number of points we need to add them .

so, (-20)+15+7

= +2

so , team a scored 2 points.

team B scored=(-10), 11, 5

again we will repeat the process by adding.

(-10)+ 11+ 5

= 6

so , team b scored 6 points.

team C scored =0, -40, 29

0+ -40+29

= -11

so , team c scored -11 points.

6 is the maximum number of points, so team B scored highest.

the scores are = 2,6,-11

so the order is = 6>2>-11

the order is = team B>team A>team C

hope this helped.
