Answer:
x = 8.33
Explanation:
y varies directly with x if y can be calculated as a constant k times x. So:
y = k*x
If y is equal to 75 and x is equal to 25, we can calculate the value of k as:
[tex]\begin{gathered} 75=k\cdot25 \\ \frac{75}{25}=\frac{k\cdot25}{25} \\ 3=k \end{gathered}[/tex]Therefore, y = 3*x
So, to find x when y = 25, we need to replace y by 25 and solve for x as follows:
[tex]\begin{gathered} 25=3\cdot x \\ \frac{25}{3}=\frac{3\cdot x}{3} \\ 8.33=x \end{gathered}[/tex]Therefore, x is equal to 8.33
