Which relationship is always correct for the angles m, n, and p of triangle abc? a triangle abc has angle abc labeled as n, angle bca labeled as p, and the exterior angle at a labeled as m. n + p = m m + p = n m + p + n = 180 degrees m + p + n = 90 degrees

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
