Answer:
I am thinking c, but I do not know
Step-by-step explanation:
I am sure but if not c then b
Train B reaches station B after 312 h
v = -3
1) Expand.
3v + 4v - 8 = -29
2) Simplify 3v + 4v - 8 to 7v - 8.
7v - 8 = -29
3) Add 8 to both sides.
7v = -29 + 8
4) Simplify -29 + 8 to -21.
7v = -21
5) Divide both sides by 7.
v = -21/7
6) Simplify 21/7 to 3.
I BELIEVE ITS C
