Dianne's profit from selling magazine subscriptions varies directly with the number of subscriptions sold. dianne made $30 from selling 24 subscriptions. which equation relates dianne's profit (y) to the number of subscriptions she sold (x)? a) y = 4 5 x b) y = 1.25x eliminate c) y = 5 4x d) x = 20xy

yes. we do proportions in probabilities.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

first one because it can't have a fraction in it
