BlackZzzverrR [31]

Answer:

The average weight of a newborn otter is 1.775 kg.

Step-by-step explanation:

We are given the following in the question:

Weight of newborn otter =

$\dfrac{7}{8}\text{ kg}$

Let x lg be the average weight of a newborn otter.

Thus, we are given the relation:

$\dfrac{7}{8} = x - \dfrac{9}{10}\\\\x = \dfrac{7}{8} + \dfrac{9}{10}\\\\x = \dfrac{35+36}{40} = \dfrac{71}{40}\\\\x = 1.775\text{ kg}$

Thus, the average weight of a newborn otter is 1.775 kg.
