Answer:
The unit rate in minutes per miles be 8.02 minutes per miles .
Step-by-step explanation:
Step 1. 26.2 miles/ 210 mins = x miles / 1min
1 * 26.2 / 210 = .12 miles / min
Step 2. 26.2. 0.13
÷210.
210. 1
(The amount miles ran in 1 minute is 0.13 miles.)
Step 3. 26.2/210= .125 miles per minute
210/26.2= 8.02 minutes per mile
Step 4. 1) Cross multiply. (26.2 = 210x)
2) Divide 210 from each side. (26.2/210 = .1247619048 , 210x/210 = x)
3) Round to the nearest 100th. (.12)
4) X=.12
5) .12 miles ran per minute
One fifth is the same as

and 15 is the same as

So just times across,

×

Resulting in(1 x 15= 15, and 5 x 1= 5),

If you need/want to reduce it, divide both numbers by 5. Leaving you with the simplified answer of

or 3. Either answer works. :)

Answer:
18
Step-by-step explanation:
Since the interior is 720 divide it by 180 and you will get 4 so 4=n-2 where the n means number of sides. Move the 4 over to n=4+2 and you get n=6
Answer:
Plug x-7 in for y, in the bottom equation.
x - 7 = 2 + 2x - 4
x - 7 = 2x - 2
x = 2x + 5
-x = 5
x = -5
