Answer:
8.4
Explanation:
Make v the subject of the 'formula, by placing 6 towards the other side.
This can be done by multiplying 6 in both sides, so the left side of the formula is 7/5 * 6, while the right is remained with v/1 (since 1/6 * 6 is 1).
Now v = 7/5 * 6 which equals to: 8.4.
Question also says round to the nearest tenth, 8.4 is already rounded to the nearest tenth so the final answer is 8.4
