Answer:

Option B.  [tex]15/8[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]

step 1

Find the value of k

we have

For [tex]x=5, y=12[/tex]

substitute

[tex]k=y*x[/tex]

[tex]k=12*5=60[/tex]

The equation is

[tex]y*x=60[/tex]

step 2

Find the value of x when y=32

substitute the value of y in the equation and solve for x

[tex]y*x=60[/tex]

[tex]32x=60[/tex]

[tex]x=60/32[/tex]

Simplify

[tex]x=15/8[/tex]
