if you go around a track one time thats 400 meters but if you go around 4 times thats 1600 meters, you dont need to use 3.14 pi for this " no offense", i do track and field myself and i do the short distance, which is 100 meters and 200 meter but for for long distance runners they go around the track 4- 8 times so it is 1600 meters is ur answer. and when u go around 8 times, thats 3200 meters.
19 - 4 = 15 baskets made in those last three games. If the same number of baskets were made in those three games, she made five in each game, because 5 + 5 + 5 = 15 (the number of baskets made in those final three games). Thus 5 baskets per game is the answer. Hope this helps!
If we add the equations it looks like -5y + 8x + 5y + 2x = -18+58 so 10x=40 so x=40/10=4 now let's replace x by 4 in the second equation 5y +2*4=58 5y=58-2*4=58-8=50 so y=50/5=10 so (x, y) = (2, 10)
