En cuál de los siguientes procedimientos se resuelven sin error las siguiente operaciones?
myrzilka [38]

D. \frac{(8)\cdot (-7)\cdot (6)}{(-4)\cdot (-2)\cdot (-3)} = \frac{-336}{-24} = 14

Por álgebra, recordamos los siguientes dos teoremas llamados teorema del signo para productos:

(-x)\cdot y = x\cdot (-y) = -x\cdot y, \forall \,x,y\in \mathbb{R} (1)

(-x)\cdot (-y) = x\cdot y, \forall \,x,y\in \mathbb{R} (2)

Basados en la información dada en la imagen y los teoremas descritos arriba, el producto del numerador debe ser negativo y el producto del numerador debe ser también negativo, más el resultado de la división debe ser positiva.

Por tanto, la opción D representa a la operación libre de errores.

Three years ago Tom was twice as old as Jean, and in two years the sum of their ages will be 28 years. Find their present ages.
lubasha [3.4K]

Answer:

Jean is 9 and Tom is 15.

Step-by-step explanation:

3 years ago, Tom was 12 and Jean was 6, hence Tom was twice as old as Jean.  

Since that was their age 3 years ago, they are currently 15 (Tom) and 9 (Jean).  

Add 2 years to each of these ages, you get 17 and 11.

17 + 11 = 28
