Answer:
280 + 12x ≤ 300
Step-by-step explanation:
A group of 20 adults and x students will visit the Museum of Science and History.
Each adult ticket costs $14 and each student ticket costs $12.
If there are maximum $300 to spend on ticket purchasing, then the inequality that gives the number of student tickets can be purchased will be
⇒ 280 + 12x ≤ 300 (Answer)

Answer:
Step-by-step explanation:
A linear pair are two given angles whose sum is equal to .
Let the exterior angle be represented by , and the three interior angles of the triangle be represented by
,
and
.
Assume that the vertex angle is the linear pair to the exterior angle
.
i.e +
=
(sum of angles on a straight line)
Thus,
i. +
=
(sum of two opposite interior angles is equal to an exterior angle)
