Answer 1

Answer:

Team A

Step-by-step explanation:

Team A total points = 40+50+30-10

                                 = 40+40+30

                                 = 110

Team B total points = 40+30-30-20

                                 = 70-50

                                 =20

=> 110 > 20

Answer 2

Answer:

Team A

Step-by-step explanation:

Team A scored = —40+30+50+(—10)

—40+(—10)= —40—10=—50

30+50=80

—50+(80)=30

Team B scored = 30+(—20)+(—30)+40

—20+(—30)=—50

30+40=70

70+(—50)=20

Team A won the quiz.
