Answer:
Step-by-step explanation:
Begin by filling in x as -2 and y as √12 in the given expression:
. Work inside the parenthesis first and deal with those exponents:
(-2)³ is the same as (-2)(-2)(-2) which is -8;
(√12)² is the same as (√12)(√12) which is √144 which is 12.
Filling those simplifications in:

Basically you just have to do either $18/4 or $27/6 which gets you to 4.5 which is the unit rate

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
