The value of x when y is 14.4 is 5.
It is given that
y ∝ 1/x
y = k/x....(1)
Where k is a constant of proportionality
<h3>What is the constant of proportionality?</h3>
The constant of proportionality is the ratio that relates two given values.
When y =6, x=12
Means, 6 = k/12
k = 72
Putting the value of k in equation (1)
y = 72/ x
14.4 = 72/ x
x = 5
Therefore, The value of x when y is 14.4 is 5.

Answer:
2.25 radians
Step-by-step explanation:
First we need to find the length of the circunference, using the formula:
C = 2 * pi * r
Where r is the radius. Using r = 8, we have:
C = 2 * pi * 8 = 50.2655 cm
Now, to find the measure of the central angle related to that arc of 18 cm, we can use a rule of three, knowing that the whole circunference has a central angle of 2pi radians:
2pi rad -> 50.2655 cm
x -> 18 cm
x = 18 * 2pi / 50.2655
x = 2.25 rad
Multiply out the brackets so that (2x-6)=7
7+6=13 divide 2=6.5
x=6.5 g
