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
In math Base is Defined as the number of digits or combination of digits that a system of counting numbers used to represent numbers a base can be any whole number greater than 0
40s=360+30a
40s+30a=$3960
40s=360+30a
40s/40=360+30a/40
s = 9+3/4a
40(9+3/4a) +30a=$3960
360+30a+30a=$3960
360+60a=$3960
360-360+60a=$3960
60a=$3960
60a/60 = $3960/60
a= $60
The algebra book is $60
