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.

Airida [17]

Answer: The boxer lose 1.8 kg in the final week to get able to compete as a flyweight.

Step-by-step explanation:

Since we have given that

Quantity of weight a boxer needs to lose in a month is given by

3\frac{1}{2}\ kg\\\\=\frac{7}{2}\ kg=3.5\ kg

In 3 months, he lowers his weight from 55.5 kg to 53.8 kg.

So, Quantity of weight he lose in three months is given by

55.5-53.8\\\\=1.7\ kg

Number of kilograms the boxer lose in the final week to be able to compete as a flyweight is given by

3.5-1.7\\\\=1.8\ kg

Hence, the boxer lose 1.8 kg in the final week to get able to compete as a flyweight.
