A system of linear equations with no solution means that the lines never meet. So as long as your two lines have the same slope and different intercepts, they will be parallel.
Ex.) y= 2x + 5
and y=2x + 10
to have a solution, the lines have to cross at a point. so literally any two lines that aren't parallel.
Ex.) y= 3x + 1
to find the solution you start by setting the equations equal to each other
2x + 5 = 3x + 1
1) subtract 2x from both sides
5= x + 1
2) subtract 1 from both sides
4 = x
now we know the x value of the point is 4. To find the y value plug 4 into one of the equations
2(4) + 5
8 + 5
13
so the solution to this particular system is (4,13)
The answer is 4.5.
The formula for a rectangle is A = lw. Substitute the formula, so it'll be 27 = (2x - 3) * x. Evaluate the formula.

Answer=12%
The lower the percent, the more unlikely that the event will happen. Since 12% is the lowest percent, it is also the most unlikely of the options.
