Answer:
Step-by-step explanation:
- <em>Let the distance is </em><em>d</em><em>, speed is </em><em>s</em>
<u>As per given we have:</u>
- d/s = 5
- 36/s + (d - 36)/(s + 3) = 5 - 1/4
<u>Substitute d with 5s and solve for s:</u>
- 36/s + (5s - 36)/(s + 3) = 19/4
- 36(s + 3) + s(5s - 36) = 19s(s + 3)/4
- 4(36s + 108 + 5s² - 36s) = 19s² + 57s
- 20s² + 432 = 19s² + 57s
- s² - 57s + 432 = 0
- s² - 9s - 48s + 432 = 0
- s(s - 9) - 48(s - 9) = 0
- (s - 9)(s - 48) = 0
- s -9 = 0 ⇒ s = 9 km/h
- s - 48 = 0 ⇒ s = 48 km/h
The original speed of grey wolf can be 9 km/h or 48 km/h
Answer:
cool im fatter
Step-by-step explanation:
-2x+6= 28
you want to get (2x) by itself so you subtract 6 from 28 on both sides
-2x= 22
then you want to get x by itself so you divide 2 on both sides
X= -11

Well if it's $112 less and the price is now $478. You just have to add $112 to $478= $590.
