People were timed while completing two different puzzles. There are 150 people that completed the first
puzzle and the mean time was 16 minutes. There are
200 people that completed the second puzzle and the
mean time was 13 minutes. Calculate the mean time of
the 350 people. Round decimals to the nearest tenth.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
