Tell whether the angles are adjacent or vertical. Then find x

ki77a [65]

The Angles are adjacent and since they are both on a straight line it means that the sum of the angle is 180 degrees, so we get the equations:

$(6x) + (x - 2)=180\\7x = 182\\x=26$

So x = 26.

Hope that helps!

Sea World has 9 aquariums with small fish in them and the number of fish in each tank are shown below: 45, 10, 48, 19, 36, 25, 6

crimeas [40]

Answer:

Step-by-step explanation:

To find the range, subtract the lowest number from the highest number

Arrange the numbers from least to greatest

45, 10, 48, 19, 36, 25, 63, 14, 37

10, 14, 19, 25, 36, 37, 45, 48, 63

The highest number is 63, and the lowest is 10

Now, subtract the lowest (10) from the highest (63)

highest - lowest

63-10

So, the range of the number of fish is 53
