Answer:
1. B-555
2. -532
Step-by-step explanation
1. Since Ana is 555 years younger you would have to find the difference between their ages, since Ana is younger you would subtract her age, B, from her sister's, Beatriz age, who is 555 years older.
2. If Beatriz is 23 and Ana is 555 years younger you just subtract 555 from 23, which is negative 532
Team Tackle scored 31 points more than Team Sack so if we take 31 away from 65 then we have 34. We then divide that by 2 for each teams score for 17 for each team. We add 31 back to Team Tackles score and we get 48 so the scores were 48 to 17
-3|2x + 6| = -12
-6x - 18 = -12
-6x = 6
x = -1
