Answer:
D one solution.
Step-by-step explanation:
It's linear. It is going to have at most 1 solution
8 + x/6 = x/6 - 4 + 5x/12 Subtract x/6 from both sides
8 = -4 + 5x/12 Add 4 to both sides
8+4 = 5x / 12 Combine
12 = 5x / 12 Multiply both sides by 12
12 * 12 = 5x * 12 / 12 Cancel
144 = 5x Divide by 5
144/5 = 5x/5
28.8 = x
Ok so what we have to do is 4+7+9=c
4+7=11
11+9=20
c=20
your answer is 20
B. End of the reconstruction.
I think it would be 3.19.
Dividing 25.52 by 8.
I believe it would be a to X is 20 units because A to B is 10 units so a to X would make sense if it was 20 units hope this helps!
