Answer:
w= 6
Step-by-step explanation:
I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.
L= 2w - 5
I used 6 as a random, educated guess for the value of w.
L = 2(6) - 5
L = 12-5
L = 7
Then, multiply L by 2 to account for both side lengths of the rectangle.
7(2)= 14
Subtract that value from the total perimeter to find what the width must equal.
26 - 14 = 12
Divide that answer by 2 since there are two sides for width.
12/2 = 6
I know this was kind of long, but I hope it helps! :)
Answer:
multiply by feet per mile and divide by seconds per hour
Step-by-step explanation:
To get the desired units, multiply by a factor that is equal to 1, but has the desired units in the numerator and the units you're converting from in the denominator.
For units in the denominator that you want to change, use the inverse of the above multiplier.
We have miles/hour, which has miles in the numerator. We want feet/second, which has feet in the numerator, so we need to multiply by the ratio of feet per mile: 5280 ft/mi.
We also have hours in the denominator, where we want seconds. So, we divide by the factor 3600 s/h.

Answer:
2160°
Step-by-step explanation:
The sum of interior angles of a convex n-gon is ...
angle sum = 180(n -2)°
When n=14, the angle sum is ...
angle sum = 180(14 -2)° = 2160°
You will first change the percentage into a decimal. This will turn out to be 0.0975. Next, you take that decimal and do 691.99 times 0.0975. You will then get 67.46902... You then add that number with 691.99. That is the answer. You should get 759.46. (This is rounded to the nearest cent.
The answer is 19/14x + 97/56 :)
