Answer 1

Given :

Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit.

To Find :

Which measurement is in pounds, and which is in kilograms.

Solution :

We know, mass in kg and pounds are related as :

$m_P = 2.2m_{kg}$

Putting, $m_{kg}=38$ and $m_P=84$ , we get :

LHS = 84

RHS = 2.2 × 38 = 83.6 ≈ 84

Since, LHS = RHS .

Therefore, 38 units is Kg and 84 units in Pounds.

Hence, this is the required solution.
