Question: the answer The figure shows the intersections of three one-way streets. To keep traffic moving, the number of cars 10 per minute entering an intersection

the answer

The figure shows the intersections of three one-way streets. To keep traffic moving, the number of cars 10 per minute entering an intersection must equal the number exiting that intersection. Write an equation Cars/min Cars/min for intersection 12 that keeps traffic moving. 12 12 10 Cars/min Cars/min 4 8 Cars/min Cars/min . . . Write an equation for intersection 12 that keeps traffic moving. Make sure to use the same variables as in the figure. (Type an equation.)
