With a problem like this, set up a proportion (like when making lemonade from a mix).
is our proportion.
We fill in the the two weights and the 24 grams of medicine in the proportion and solve for the fourth piece not there.
We shorten medicine to M and we solve for M by cross multiplying.
The woman should get 19.2 grams of medicine.
Answer:
x = 3/5
Step-by-step explanation:
4+4(x-2)=2(x+1)−x
Distribute
4+4x-8 = 2x+1-x
Rearrange and Simplify
4x - 4 = x + 1
Subtract x and add 4
3x = 5
Divide
x = 3/5
The answer will be 500,000
As far I as know
It should be A
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)...
