Acoach 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
