Answer:
C
Step-by-step explanation:

In answer c, the first term remains the same, but the second is the reciprocal of the original. Also, the operator has changed from division to multiplication, so C is the correct answer.
24 pages. 12 is half an hour (30 minutes) so just multiply it by 2 so the minutes can equal an hour (60 minutes)
2xy + 5 - 8 + 3xy - y +7 + 3y = 5xy - 8 + 2y + 12
