The minimum number of train cars needed is 8 because 112 multiplied by 8 is 896 which means 7 trains will be full and the last one will only carry 108 crates
∛(1/8 - <em>x</em>) = -1/2
Take the 3rd power of both sides and solve:
(∛(1/8 - <em>x</em>))³ = (-1/2)³
1/8 - <em>x</em> = -1/8
2/8 = <em>x</em>
<em>x</em> = 1/4
You can't unless you have other information.
Hope this helps :)

Answer:
First number = 33, Second number = -19
Step-by-step explanation:
We can use F to represent the first number and S to represent the second number.
Our two equations then are F + S = 14 and 2F + 3S = 9
We can use substitution:
