18 divided by 30 is 0.6. So I would say that B, or 0.6, is the correct answer.
Answer:
![12.5(x + 20) = 460 \\ x + 20 = 460 \div 12.5 \\ x + 20 = 36.8 \\ x = 36.8 - 20 \\ x = 16.8](https://tex.z-dn.net/?f=12.5%28x%20%20%2B%2020%29%20%3D%20460%20%5C%5C%20x%20%2B%2020%20%3D%20460%20%5Cdiv%2012.5%20%5C%5C%20x%20%2B%2020%20%3D%2036.8%20%5C%5C%20x%20%3D%2036.8%20-%2020%20%5C%5C%20x%20%3D%2016.8)
Hence, 16.8 miles is your answer
2.5x + 4x = 39
6.5x = 39
x = 39 / 6.5
x = 6
This is a pythagorean triple --> 3-4-5
Although you notice it is doubled but with the same pattern --> 6-8-10
Thus, the hypotenuse is 10.
Answer:
Step-by-step explanation:
Let us have y as the output and x as the input
5 is less than twice the input
twice the input is x * 2 = 2x
so we have 2x-5
