For this question I'm just going to use / as a square root sign because I don't know how to do it on a computer. Anyways...
So you have /45
Now you have to find a factor that is also a perfect square which is 9 (because 9x5=45)
So you now have /9x5
Since 9 is a perfect square (/9=3)
You can re write it is 3/5 which is the answer
First, you want to get x by itself on one side. We write the equation as

. Since 14 is being subtracted from

, we add it to both sides to cancel it out,

or

.
Your answer would be D.
Step-by-step explanation:
Let the length be x
7% of x = 200ft
7/100 × x = 200
7x/100 = 200
7x = 200 × 100
7x = 20000
x = 20000/7
x = 2,857.14
Answer:
7
Step-by-step explanation:
Data of # posts made:
1, 1, 2, 2, 3, 5, 5, 6, 7, 7, 7, 8, 8, 9, 9, 9, 9, 10
Since we want to find the median, we find the middle number which is 7. The median is 7.
