D. 60%
Step-by-step explanation:
Of the 65% who study either time, 47% study on weekends. That means 65%-47% = 18% study on weeknights only.
The fraction who study on weeknights is the total of the fraction who study on weeknights only (18%) and the fraction who study on weeknights and weekends (42%). That total is ...

Answer: 11
Step-by-step explanation:
Complementary angles mean both angles sum 90°, then:
(3x + 2)° + 5x° = 90°
3x° + 2° + 5x° = 90°
8x° + 2° = 90°
8x° = 88°
x = 11
Confirmation:
(3x + 2)° 5x°
(3(11) + 2)° 5(11)x°
(33 + 2)° 55x°
35°
35° + 55° = 90°
