Answer:
-3
Step-by-step explanation:
Simplify the following:
(-9 (-5) - 9)/(-12)
-9 (-5) = 45:
(45 - 9)/(-12)
| 3 | 15
| 4 | 5
- | | 9
| 3 | 6:
36/(-12)
The gcd of 36 and -12 is 12, so 36/(-12) = (12×3)/(12 (-1)) = 12/12×3/(-1) = 3/(-1):
3/(-1)
Multiply numerator and denominator of 3/(-1) by -1:

72-54 =2a
A=9
A+54= 3a+b
63=3a+b
63= 3(9) +B
B=36
A+B =C
9+36=45
C=45
A+2C=4a+2D
9+ 2(45) = 4(9) + 2D
63=2D
D=31.5
A+D=F
9+31.5=F
F= 40.5
