Hey!
Hope this helps...

To solve this, we will be doing a semi-alternate route, but it will get us to our answer...
400 / 100 = 4
30 / 4 = 7.5 seconds
60 * 60 * 7.5 = 27,000 meters per hour
<em></em><em>Lets plug it into our meters to miles formula...</em>
27,000 / 1,609.344 ~ 16.777 miles per hour
So...
The answer is: The Polar Express was going 27,000 meters per hour (or roughly close to 16.777 miles per hour)...
Answer:

Step-by-step explanation:
Answer:
Multiples of 2/3 are 4/3, 2, and 8/3
Step-by-step explanation:
Answer:
-4.4
Step-by-step explanation:
In order to do this, we need to move the variables to one side, and the numerical values to the other.
-20-7x=-2x+2
We can do this by adding 7x to both sides first
-20=5x+2
Now we can subtract 2 from both sides.
-22=5x
Next, we can divide each side by 5.
x=-22/5
Then we simplify the fraction
x=-4.4
Answer:
the value of x will be 7.1 when y = 12
Step-by-step explanation:
first you would find the difference between the y value 8.4 and see how far it is from 12. you should get 3.6 after that, add 3.6 and the x value and that'll give you your x for when y = 12.
