Answer 1

Answer:

mark as brainlist if it helped

Step-by-step explanation:

round 1 = 10

round 2=20

round 3 = ? (lets take it as x)

round 4 = 40

round 5 = 50

final score = 60

so the sum of scores of all the rounds is 60

10+20+40+ 50 + x = 60

120 + x = 60 (x and 60 change places signs change)

120-60 = -x

60= -x

x = - 60

round 3 = - 60
