Answer:
Step-by-step explanation:
-x^2 - 6x + 5=0
Your race car can travel 1/4 mile in 3.12 seconds. what is the average speed of you race car in miles per hour. In order to calculate the speed of the car we first have to identify the suited formula for distance in this scenario.
<span>
Hence, d = 0.25 mi T = 3.12 seconds
Solution:
velocity = distance / time
</span><span>velocity = 0.25</span><span> mi / 3.12 s
velocity = 0.08 mi/s

1. Make the equation. The product of the number and 6 equals the sum of the number and 45, so the equation would be 6x = x + 45.
2. Subtract x from both sides. You'll get 6x - x = 45.
3. You can combine like-terms by subtracting 6x - x. This is the same as 6x - 1x, which is 5x. You'll get 5x = 45.
4. Divide both sides by 5 to get x = 9.
Therefore, the number is 9.
