Answer:
(a) 20 + 14(s)
(b)$146
Step-by-step explanation:
Use s as your variable per session.
$20 is a flat fee as a sign up for tutoring.
Therefore, 20 + 14s is the expression.
(b) 14x9=126 + 20 = 146
One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees
so total measure of all angles in octagon = 8 * 135 = 1080 degrees

Answer:
Multiple of 9
Step-by-step explanation:
Because 72 = 9 x 8
and 9 x 12 = 108
The answer is 48 units. You do 36 / 75% it is 48. You can also check your answer by doing 48 times 75%, which would equal 36.
