-------------
P = 5 watts * 30 minutes * 60 sec/minute
P = 9000 watt-seconds = 9000 Joules

--------------
Put 3x+8y=5 into slope-intercept form.
That means solve for y.
--------
3x+8y=5
y = (-3/8)x + 5/8
----
The slope is -3/8
All parallel lines have the same slope, -3/8
---------
The slope of lines perpendicular is the negative inverse, = +8/3
------
That's all there is to that.

----------------
You can solve for either first. Pick the one that's easiest.
x-6y= -51 --> x = 6y - 51
Solving for y would cause fractions.
----------
Sub for x in 3x-7y= -54
3(6y-51) - 7y = -54
18y - 153 - 7y = -54
11y = 99
y = 9
==========================
Sub for y into any equation to find x.
x-6y= -51
x - 6*9 = -51
x = 3
That's it.

--------------
Area = L*W
1/12 = W*2
W = 1/24 yd

-----------
It's not 3rd power square root, it's cube root.
-------
 =~ 3.41995
So it's between 3.41994 & 3.41996
----
If you meant integers,
