Let x represent the smaller angle. Then the larger one is 20+4x. Since they are complementary, their sum is 90. (All measures are degrees.)
90 = x + (20+4x)
90 = 5x +20
70 = 5x
14 = x
The smaller angle is 14°.
The larger angle is 76°.
1/2 = 8/16 . . . so there are (<u><em>8</em></u>) - 1/16 pounds servings of chocolate in a 1/2 pound chocolate bar
1 hour = 60 minutes
60 minutes / 10 minutes = 6
So 6 times in one hour 3 buses depart.
6 x 3 = 18 total buses in an hour.
First introduce the following notations:
3 / (1/8) = 3 × (8/1) = 24
There needs to be 24 students on a team.
