Question

1.) If x varies directly as y and x = 35 when y = 7. What is the value of y when x = 25?​

Answer 1

y = 5

Explanation:

`x \ \alpha \ y`

`=> x = k * y\\=> 35 = k * 7\\=> k = 5`

`x = k * y`

`=>25 = 5 * y\\ =>5 = y`

Answer 2

y = 5

Explanation:

x = 35, y = 7

x = ?y

35 = ?7

? = 5

x = 25, y = ?

x = ?y

25 = 5y

y = 5
