Does that make sense?
The weight in kilograms of an object that weighs 70 pounds is 31.5 kilograms.
<h3>How to calculate the value?</h3>
Given that the number of kilograms that an object weighs varies directly with the number of pounds and that an object weighs 45 kilograms weighs 100 pounds.
This will be:
y = mx
y = weight in kilograms
x = weight in pounds
k = constant
45 = 100k
Divide
k = 45/100
k = 0.45
The equation will be written as y = 0.45x
Therefore, when the object weighs 70 pounds, this will be:
y = kx
y = 0.45 × 70
y = 31.5
The weight in kilograms is 31.5kg
