Answer:A system of linear equations usually has a single solution, but sometimes it can have no solution, or infinite solutions.One solution. A system of linear equations has one solution when the graphs intersect at a point.
Step-by-step explanation:
There really is no way of telling. If the 51 got 100, then the rest could have gotten anything. If there is no graph, or data, or anything else to support the question, that means the 27 could have gotten any mark.

5
Step-by-step explanation:
You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.
The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.
We can deduce that, if x is the number of people between 16 and 19, we have

So, by the relation between the two graphs, we can deduce the total population for each age group.
The answer is D. Linear equation
