Answer: feet: 1, 2, 3, 4, 5
inches: 12, 24, 36, 48, 60
Step-by-step explanation:
There are 12 inches in a foot, therefore if you have 1 foot you have 12 inches, if you have 2 feet you have 24 inches becauase 2*12 = 24 and so on...
16-18=-2
You can use a number line to help you.
The system of equations does not have a solution.
For example, imagine these two equations y = x + 7 and y = x + 9
Now subsitute y in the second equation with the value from the first equation:
x + 7 = x + 9
x - x + 7 = 9
0 + 7 = 9
7 = 9.
That happens because the equations represent parallel lines, which do not have a common pair of points.
Answer:
The answer is "0.45385".
Step-by-step explanation:
The time is taken to reach the coast
The time is taken to reach Q after reaching the coast 
Total time,
This has to be minimum,


x=0.45385
We are going to name the people A, B, C, and D
1. A, B, C, then D
2. A, B, D, then C
3. A, C, B then D
4. A, C, D, then B
5. A, D, B, then C
6. A, D, C, then B
So at this rate, if there is 6 for the first letter, then there will be 6 for the others, so 6 x 4 = 24, so there are 24 different outcomes.
Hope this helped!
