<span>Two lines are parallel if their slope is the same.
You want to write 8x + 4y = 5 in the form y = mx + b, where m represents the slope and b is the y-intercept.
We need to isolate y in the given equation. The number next to x is the slope.
8x + 4y = 5
4y = -8x + 5
y = (-8x +5)/4
y = -2x + 5/4
The slope of the line we want is -2.
Two lines are perpendicular if the slope of the first line times the
slope of the second line produces a product of negative one.
Since our slope is -2, we know that -2 times 1/2 yields -1.
The slope of the line perpendicular is 1/2.

Answer:
20/156 or 5/39
Step-by-step explanation:
the first part of the equation will be:
5/13 (5 is how many blue and 13 is altogether)
the next part of this equation is the green marble. Because we didn't put the blue marble back, the next part of the equation will be:
4/12 (4 is how many green and 12 is altogether now that one blue was taken out)
and from there, you multiply 5/13 with 4/12, with will give you 20/156, or 5/39 if you simplify.
