A coach needs both small and large cones to set up an obstacle course. He knows there are fewer than 30 cones in the storage room. He needs at least a dozen large cones. Let x represent the number of small cones and y represent the number of large cones.
 Which inequalities model the situation?
 Choose exactly three answers that are correct. 
 (Points : 1)
 x + y < 30 
 x + y ≤ 30 
 y > 12 
 y ≥ 12 
 x > 0 
 x ≥ 0
