The first arrow has a closed circle which indicates greater/less than or equal to. All the values shaded are to the left of 0. So, x is less than or equal to 0. The second arrow also has a closed circle. Since the shaded part of the arrow is to the right of 7, x is greater than or equal to 7.

58 is 20% of having trouble

ella [17]

First, let's introduce a variable:

Let n represent the number we are trying to find.

20 % x n = 58
0.20 x n = 58
0.20n = 58
n = 290

Therefore, 58 is 20% of 290.

Hope this helps!
Message me if you have any questions. :)
