It will take 15 hours. Because the train has a speed of 18 mph, you just have to divide 270 by 18 which makes 15. The train goes 18 mph, so it is 15 hours.
Answer:
x=4,y=9
Step-by-step explanation:
We want to solve the equation:


simultaneously.
Multiply the top equation by 3 and the bottom equation by 2 to get:
6y-15x=-6
6y+4x=70
Subtract the top equation from the bottom equation.




We substitute x=4 into 2y-5x=-2 to get:



Therefore the solution to the system is
(4,9)
Answer:
x Superscript 9 Baseline (RootIndex 3 StartRoot y EndRoot)
OR x^9/(∛y)
Step-by-step explanation:
Given the indicinal equation
(x^27/y)^1/3
To find the corresponding expression, we will simplify the equation as shown:
(x^27/y)^⅓
= (x^27)^⅓/y⅓
= {x^(3×9)}^⅓/y⅓
= x^9/y⅓
= x^9/(∛y)
The right answer is x Superscript 9 Baseline (RootIndex 3 StartRoot y EndRoot)
1.) It would be: 12/600 * 100 = 12/6 = 2
So, your final answer is 2
2.) It would be: 20 * 0.15 = 3
So, your final answer is 3
Hope this helps!
