Answer:
B. 12 slats
Step-by-step explanation:
Divide 42 by 3.5 and you get 12.
<span>Simplifying
15.36x[-0.45] = 0
Reorder the terms for easier multiplication:
15.36 * -0.45x = 0
Multiply 15.36 * -0.45
-6.912x = 0
Solving
-6.912x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-6.912'.
x = 0
Simplifying
x = 0</span>
That doesn't seem entirely correct. It's the ideal gas law, but PV can't be the same as nrt and nrtPV times itself.
The correct one should be:
p * V = n * R * T
Then you can solve it for T.
(p * V)/(n*R) = T
