Answer:
see explanation
Step-by-step explanation:
Given that y is inversely proportional to x then the equation relating them is
y =
← k is the constant of proportionality
To find k use the condition that y = 7, x = 9
k = yx = 7 × 9 = 63, thus
y =
← equation of proportion
When x = 21, then
y =
= 3

Answer:
B) 7/9
Step-by-step explanation:
<h3>Fraction addition:</h3>
- If the denominators are not same, find the LCM of the denominators.
