sprints: 1/8 of 74 1/2 = 74.5 divided by 8=9.3125
Hunts: 3/4 of 57 3/4= 57.75 divided by .75=77
9.3125 + 77=86.3125 86.3125 divided by 2= 43.156 mph average speed
Answer:
Up to 5 hours
Step-by-step explanation:
<u>Given:</u>
- One off fee = $46
- Hourly rent = $6.4 / hr
- Amount limitation= $78
<u>Equation to reflect the condition:</u>
- 78 = 46 + 6.4t
- 6.4t = 78 - 46
- 6.4t = 32
- t = 32/6.4
- t = 5 hours max
So, the meeting room can be rented for up to 5 hours with $78
X^2-18 = 3x
x^2 - 3x - 18 = 0
(x-6)(x+3) = 0
x = {-3,6}
So -3 is the answer
