Ketisha is practicing for a marathon by running around a track that is 440 yards long. yesterday she ran around the track 20 times. how may miles did she run

If 1 mile = 1760 yards

so you multiply 440 times 20 which is 8800.

Then you divide 8800 by 1760 and give you 5, so Ketisha ran 5 miles.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
