Answer:
Yes
Step-by-step explanation:
To see is (2, 6) is a system, we can plug it into the system to check if it gives us true statements:
6 = -2+8
6 = 6
6 = 5(2)-4
6 = 10-4
6 = 6
Both of the equations are true, therefore (2, 6) is a solution to this system.
To find her speed, divide the total distance by the total time:
12.5 miles / 5 hours = 2.5 miles per hour.
4/5, because to simplify a decimal, you can divide the numerator by the denominator. 4 divided by 5 is 0.8
