The system:
- 12 c + 3 d = 6
- 3 c + 6 d = - 9
----------------------
The 1st equation:
- 12 c = - 3 d + 6 / * ( - 1) ( multiple both sides by -1 )
12 c = 3 d - 6 / : 12 ( divide both sides by 12 )
c = d / 4 - 1/2
Answer:
C ) c = 1/4 d - 1/2
The area of the clock is 153.86(preferred)/153.94 or 49n n=pi
14/2 is 7 7*7=49 49 x pi is 153.94
greater, above I hope this helps out!
V = Bh ⇒
h = V/B = 1122 / 93.5 = 12 inches.
