Parenthesis first

19- (4+2) - 15 / 3

19-(6)-15 / 3

then division

19-6-5

then subtraction from left to right. 

19-6= 13
13-5= 8

your final answer is 8

The answer is 8. Using PEMDAS is really helpful and you can come up with sayings so like I always used "Please Excuse My Dear Aunt Sally" so parentheses, exponents, multiplication, division, addition, subtraction.

Los dueños de un restaurante cultivan sus propios
zzz [600]

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:

V=(1/3)\cdot V_0=(1/3)\cdot6.25\,m^3=2.083\,m^3

Este valor equivale a un volumen en litros de:

V=2.083\,m^3\cdot \dfrac{1,000\,l}{1m^3}=2,083\,l
