Answer:
200 berlindes
Step-by-step explanation:
Vamos representar
O número total de berlindes na caixa = X
Mármores vermelhos = 20% de X
= 0.2X
Mármores amarelos = 40% de X
= 0.4X
Mármores azuis = 80
Conseqüentemente,
0.2X + 0.4X + 80 = X
Recolher termos semelhantes
80 = X - 0.2X - 0.4X
80 = X - 0.6X
80 = 0.4X
Divida ambos os lados por 0.4
X = 80 / 0.4
X = 200
Uma vez que X representa o número total de berlindes na caixa, portanto, o número total de berlindes na caixa = 200 berlindes
