Answer: Stephanie is the fastest
Step-by-step explanation:
Here we have to find who runs faster:
Liz:
![8 ft/s](https://tex.z-dn.net/?f=8%20ft%2Fs)
Katie:
![\frac{350 ft}{31 s}=11.29 ft/s](https://tex.z-dn.net/?f=%5Cfrac%7B350%20ft%7D%7B31%20s%7D%3D11.29%20ft%2Fs)
Stephanie:
![\frac{1 mile}{388 s}. \frac{5280 ft}{1 mile}=\frac{5280 ft}{388 s}=13.60 ft/s](https://tex.z-dn.net/?f=%5Cfrac%7B1%20mile%7D%7B388%20s%7D.%20%5Cfrac%7B5280%20ft%7D%7B1%20mile%7D%3D%5Cfrac%7B5280%20ft%7D%7B388%20s%7D%3D13.60%20ft%2Fs)
Noah:
![\frac{541 ft}{1 min}. \frac{1 min}{60 s}=9.01 ft/s](https://tex.z-dn.net/?f=%5Cfrac%7B541%20ft%7D%7B1%20min%7D.%20%5Cfrac%7B1%20min%7D%7B60%20s%7D%3D9.01%20ft%2Fs)
As we can see after comparing, Stephanie is the fastest, since she travels more distance in less time.
Answer:
C
Step-by-step explanation:
Given
- 12x - 2(x + 9) = 5(x + 4) ← distribute parenthesis on both sides
- 12x - 2x - 18 = 5x + 20, that is
- 14x - 18 = 5x + 20 ( subtract 5x from both sides )
- 19x - 18 = 20 ( add 18 to both sides )
- 19x = 38 ( divide both sides by - 19 )
x = - 2 → C
