Answer:

Therefore, when s is equal to 30, t is equal to 30 / 5 = <<30/5=6>>6.

Explanation:

Direct variation means that the ratio between two variables is always constant. In this case, the constant ratio between s and t is equal to 20/4 = 5. This means that when t is equal to 4, s is equal to 20 and the ratio between the two is 5. If s is equal to 30, we can find the corresponding value of t by setting up the following equation:

s / t = 5

We can then solve for t by multiplying both sides of the equation by t to get:

s = 5 * t

If we substitute 30 for s, we get:

30 = 5 * t

We can solve for t by dividing both sides of the equation by 5:

t = 30 / 5

Therefore, when s is equal to 30, t is equal to 30 / 5 = <<30/5=6>>6.
