Answer:
The given inequality is uncompleted.
However, we can solve each possible case,
If the inequality is , then the graph would be like the first image attached. The solution is the shaded area, which means that all pairs
that are solutions must be above the line. It's important to notice that the line is not solid, this is because the inequality symbol
doesn't include all values on the line.
If the inequality is , then the graph would be like the second image attached. You can observe that the solution here is the opposite shaded area, that's because we have now the opposite inequality sign.
If the inequality is , the graph would be like the first case, but with the difference of having a solid line.
If the inequality is , the graph would be like the second case, but with the difference of having a solid line.

Tricky question. This isn't a ratio question even though it seems like one.
First divide 7 by 4.
With more men, the hours taken to repair a road will be even shorter.
So next divide 6 by 1.75.
Answer : It'll take 3.43 hours to do the job if they work at the same rate.
Hope this helps. - M
