Answer:
Step-by-step explanation:
Alejandro has read 28 pages so far and he can read 1 page per minute.
Again, Carly has read 12 pages so far and he can read 2 pages per minute.
If the variable N represents the number of pages read by the readers and T in minutes represents the time spent by the reader to read this number of pages, then
For Alejandro: 
......... (1)
For Carly: .......... (2)
So, the equations (1) and (2) gives the number of pages that Alejandro and Carly read. (Answer)

Answer: 67°
Step-by-step explanation:
Complementary angle refers to the angle that when added together will be equal to 90°.
Let the measurement of the angle's complement be x.
Therefore, the angles are x and 2x + 21. Since it's a complementary angle, therefore,
x + 2x + 21 = 90
3x + 21 = 90
3x = 90 - 21
3x = 69
x = 69°/3
x = 23°
Therefore, the angle will be:
= 2x + 21
= 2(23°) + 21°
= 46° + 21°
= 67°
The angle is 67°.
