Question

The value of y varies directly with x, and y = 12 when x = 10. Find y when x = 25.​

Answer 1

Answer:

$y = 30$

Step-by-step explanation:

$x \: \alpha \: y$

In direct proportion, the ratio of x and y remains sme.

Therefore,

$\frac{10}{12} = \frac{25}{y}$

$y = \frac{12 \times 25}{10}$

$y = 30$
