Answer :

Certainly! Let's solve this problem step-by-step.

We are given that the ratio [tex]\( x : 50 \)[/tex] is equivalent to the ratio [tex]\( 8 : x \)[/tex]. This can be written mathematically as:
[tex]\[ \frac{x}{50} = \frac{8}{x} \][/tex]

To solve for [tex]\( x \)[/tex], we can use cross-multiplication. Cross-multiplying the two fractions gives us:
[tex]\[ x \cdot x = 8 \cdot 50 \][/tex]

Simplifying the right side, we get:
[tex]\[ x^2 = 400 \][/tex]

To find the value of [tex]\( x \)[/tex], we take the square root of both sides of the equation:
[tex]\[ x = \sqrt{400} \][/tex]

The positive square root of 400 is:
[tex]\[ x = 20 \][/tex]

Therefore, the positive value of [tex]\( x \)[/tex] that satisfies the condition [tex]\( x : 50 \)[/tex] being equivalent to [tex]\( 8 : x \)[/tex] is:
[tex]\[ \boxed{20} \][/tex]
