Answer:
322 antes de Cristo
Step-by-step explanation:
Se começarmos com o princípio de que antes de Cristo os anos são representados em uma linha real à esquerda de 0 (nascimento de Cristo) e os anos após Cristo na linha real à direita de 0, temos:
......-384.......-322..... -2,-1,0,1,2,.......................
-384+62 = -322, isto é, o ano 322 antes (-) de Cristo

Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: TEAM A
Tammy working alone in 1hr can clean 1/2
Melissa working alone in 1 hr can clean 1/3
working together in 1hr ,let x represent the area they will clean we have
+ = 1/x
⇒ 3 + 2 = 1/x
5 = 1/x
x = 1/5
TEAM B
Santay working alone can clean 1/4
Leticia working alone in 1 hr can clean 4/5
working together in 1 hr ,let y represent the amount they clean, we have
+ = 1/y
4 + 5/4 = 1/y
21/4 = 1/y
y = 4 /21
comparing x and y , 1/5 is greater than 4/21 , therefore Team A is faster
