Answer:
2.25km
Step-by-step explanation:
Calculate the total distance:
<u>9km/</u> 0.80 x 100% = 11.25km
The walker has travelled 9km, so
11.25km - 9km = 2.25km left
Distribute 9z to 7z and -4
You get 56z^2 - 36z = 6
56^2 - 36 - 6 = 0
Solve using quadratic formula
z is approx 0.78 and approx. -0.14
I agree because if your answer is in a negative that means, the number that is closer to zero is the greater number, ex: -23>-56.
Answer:
x = -12,
Step-by-step explanation:
-1 + 5/4x = -16
5/4 x = -16 + 1
5/4 x = -15
x = -15 * 4/5
