If the ratio of a model train to a real train exists 1:3 and the real train exists 12 feet then the model train exists 3 feet long.
<h3>How to estimate the ratio of the model train?</h3>
Given that the model train contains a scale of 1: 3 and the real train exists 12 feet tall.
The ratio indicates how many times one number has another number.
A ratio exists as the relationship in quantity between two things.
It conveys the quantity of one thing in words of another.
The ratio of a model train to a real train exists at 1 inch :3 inches.
Height of model train = 12
1/4
Height of model train = 3 inches
Therefore, the ratio of a model train to a real train exists 1: 3 and if the real train exists 12 feet then the model train exists 3 feet long.

Answer:
x^(6/35)
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)^c = a^(bc)
__
![(x^{\frac{2}{5}})^{\frac{3}{7}}=x^{\frac{2\cdot 3}{5\cdot 7}}=\boxed{x^{\frac{6}{35}}=\sqrt[35]{x^6}}](https://tex.z-dn.net/?f=%28x%5E%7B%5Cfrac%7B2%7D%7B5%7D%7D%29%5E%7B%5Cfrac%7B3%7D%7B7%7D%7D%3Dx%5E%7B%5Cfrac%7B2%5Ccdot%203%7D%7B5%5Ccdot%207%7D%7D%3D%5Cboxed%7Bx%5E%7B%5Cfrac%7B6%7D%7B35%7D%7D%3D%5Csqrt%5B35%5D%7Bx%5E6%7D%7D)
1=2 2=1 3=0 that is the corect answer
37=30-2x
7=-2x
-3.5=x
x=-3.5
