Answer:
The answer would be D. 38.7 miles per hour. To figure this out you must replace the d with 41 and the t with 2.3 so you get an equation that looks like this, 41=r-2.3. With this you can easily subtract 41-2.3 and you get 38.7 as the r. ;)

Answer:
0.0833...
Step-by-step explanation:
1 out of 12 can be rewritten as 1 divided by 12.
1 divided by 12 is 0.08333333...
I'm not sure how many places you want to round it to, but if you were to round it to the hundredths place you would get 0.08, and if you were to round it to the thousandths place you would get 0.083.
Hope this helps!

Answer:
w = (p - 21)/2
Step-by-step explanation:
Rearrange the equation so that it is equal to w.
p = 21 + 2w
p - 21 = (21 + 2w) - 21
p - 21 = 2w
(p - 21)/2 = (2w)/2
(p - 21)/2 = w
w = (p - 21)/2
