(27.45-14.61)-[12.53-36.75]
= (12.84) - (-24.22)
= 12.84 + 24.22
= 37.06 Answer
Answer:
Quedan 2.083 m^3 de agua en el reservorio.
Equivalen a 2083 litros.
Step-by-step explanation:
Los dueños del restaurante tienen un reservorio de agua cuyo volumen es de 6.25 m^3.
Si han utilizado 2/3 del reservorio, esto implica que aún quedan en el reservorio una tercera parte del volumen original (1/3).
Entonces, la cantidad de metros cúbicos (m^3) de agua que quedan en el reservorio se puede calcular como:
Este valor equivale a un volumen en litros de:
1/2a - 4
Add 4 to both sides.
1/2a = 4
Divide both sides by 1/2.
a = 8
