Answer:
c) 1.8 miles
Step-by-step explanation:
Assuming Kayla walks at a constant speed, we have ...
miles/minutes = 3.2/45 = x/25
x = 25(3.2/45) = 1.777... ≈ 1.8 . . . . miles
Kayla walks about 1.8 miles in 25 minutes.
Suki is correct because adrienne subtracted 6 instead of -6
Answer:
90/13, 45/13
Step-by-step explanation:
![- 2 = x \\ 7x + 9y = - 45 \\ \\ 7 \times ( - 2)y + 9y = - 45 \\ y = 9 \\ \\ 7x + 9 \times 9 = - 45 \\ x = - 18 \\ (x.y) = (- 18.9) \\ \\](https://tex.z-dn.net/?f=%20-%202%20%3D%20x%20%5C%5C%207x%20%2B%209y%20%3D%20%20-%2045%20%5C%5C%20%20%5C%5C%207%20%5Ctimes%20%28%20-%202%29y%20%2B%209y%20%3D%20%20-%2045%20%5C%5C%20y%20%3D%209%20%5C%5C%20%20%5C%5C%207x%20%2B%209%20%5Ctimes%209%20%3D%20%20-%2045%20%5C%5C%20x%20%3D%20%20-%2018%20%5C%5C%20%28x.y%29%20%3D%20%20%28-%2018.9%29%20%5C%5C%20%20%5C%5C%20)
