Answer:
Length = 3 ft
Step-by-step explanation:
If the equation for perimeter is p = 2 (L+W)
You can plug in the information you already have
1) 18 = 2 (L+6)
2) Simplify by first dividing 2 by itself to cancel it out and then by 18 which would equal 9 leaving you with the equation 9 = L+6
3) Now to leave the L alone on the right you need to cancel out the 6 by subtracting 6 from itself and then from 9 which would leave you with the equation and the answer to the problem, 3 = L
2.8 miles.
My Work/Reasoning:
First we find the rate. 7/60 mpm (miles per minutes)
Then we multiply that by 24. 7/60 * 24
Finally, we solve the equation and learn that Chang would run 2.8 miles in 24 minutes.

Answer:
examine the next digit and increase the number accordingly, before dropping the digits of no interest.
Step-by-step explanation:
You round any number by looking at the digit in the place to the right of the one you want to round to. If it is 5 or more, you add 1 to the number in the place you're rounding to, and drop (or zero) all digits to the right of that.
If you want to round this to tenths, you observe that the hundredths digit is 7, which is more than 4. So you add 1 tenth and drop the hundredths digit:
99.87 ≈ 99.9 . . . . rounded to tenths
If you want to round this to units, you observe that the tenths digit is 8, which is more than 4. So you add 1 unit and drop the tenths and hundredths digits.
99.86 ≈ 100 . . . . . rounded to nearest integer
