Jada ran 15.25 kilometers. Han ran 8,500 meters. Who ran farther?
Thepotemich [5.8K]

Answer:

Jada

Step-by-step explanation:

We are given Jada's distance in kilometers and Han's distance in meters. To compare the two we need to have them both in the same unit of measurement.

One kilometer is equal to 1000 meters, so Jada ran 15.25*1000=15250 meters.

Compared to Han, who ran 8500 meters, Jada ran farther. 15250>8500.

Answer:

(-1, -2)

Simplify:

-4x + 3x - 3 = -2

-x = 1

x = -1

Plug in x=-1 into the second equation:

y = (-1) - 1

y = -2
