Answer: D
Step-by-step explanation:
If we substitute -12 into this equation we get:
![-3[-12-8]+1.5](https://tex.z-dn.net/?f=-3%5B-12-8%5D%2B1.5)
![-3[-20]+1.5](https://tex.z-dn.net/?f=-3%5B-20%5D%2B1.5)
Because -20 is in absolute value, we simply just use 20.
Thus,

How many times does 40 go into 100 2 1/2 so multiply 23 by 2 1/2 to get 57.5 enjoy

Answer:
x = 16
Step-by-step explanation:
The angle bisector divides the sides proportionally.
(x -4)/9 = x/12
4(x -4) = 3x . . . . . . . multiply by 36
x = 16 . . . . . . . . . . . . add 16-3x to both sides, simplify
Answer: 9. n = 2 19/20 10. n = 2 1/12
Step-by-step explanation: 3 2/10-1/4 = n 32/10−1/4 32/10+−1/4 16/5+−1/4 64/20+−5/20 n = 59/20 n = 2 19/20 2 5/6-3/4 = n 17/6-3/4 17/6+-3/4 34/12+-9/12 n = 25/12 n = 2 1/12
