Answer:
tbh i really dont know
Step-by-step explanation:
The ordered pair (-1,5) is a solution to the system because it makes both equations true.
1) x+y=4
2) x-y=-6
1) -1 + 5 = 4
5-1 = 4 you can switch the order to make it easier to understand
so
4 = 4
2) -1 - 5 = -6
-1 + -5 = -6 you can change the sign in the middle and make y -
so
-6 = -6
The answer is 4 hope this helps
For 2/5 meter, it takes = 1 min.
For 1 meter, it is = 5/2 min.
Now, for 6 meters, it would be: 5/2 * 6 = 30/2 = 15
In short, Your Answer would be 15 minutes
Hope this helps!
