Answer: -1
Step-by-step explanation:
− 0.25(−8+12) = -0.25 x 4 =-1
2.5-3.5x= 8-(4x+6)
⇒ 2.5-3.5x= 8- 4x -6
⇒ -3.5x+ 4x= 8 -6 -2.5
⇒ 0.5x= -0.5
⇒ x= -0.5/0.5
⇒ x= -1
Final answer: x= -1~
I think that it is B and C

I hope this helps! Let me know if you would like an explanation as to how I got the answers :)
The answer is 3/2.
Explanation: you want to get x by itself so that you have the equation x = 15. To do that you multiply 2/3x * 3/2 to get x. this works because 3/2 cancels out 2/3 and you get 1. Multiplying 10 by 3/2 also gets you 15. So in the end you have
x = 15.
