Answer:
x > 8.125 or 8 & 1/8
Step-by-step explanation:
8( -x - 7) > 16
-8x - 49 > 16
+ 49 + 49
-8x > 65
x > 8.125 or 8 & 1/8
Answer:
8x2=16 9x7=63
63+16=79
Step-by-step explanation:
Answer:
35cm
Step-by-step explanation:
The net of a regular pentagon has 10 sides.
Since each of the faces are equilateral triangles, the side lengths are equal.
Therefore:
Length of each side of the net = 70/10 =7cm
Therefore, the base is a regular pentagon of side length 7cm.
The perimeter of the base of the pyramid = 5 X 7
=35cm
The perimeter of the base of the pyramid is 35cm.
The mean is the same thing as the average. To find the average, add all the numbers up (aka find the sum of the numbers) and divide by how many numbers there is:
So the sum of your numbers is: -6 + 2 + 5 + -7 + -11 + -6 = -23. And there are 6 numbers total.
That means average =
≈ -3.8
Your final answer is -3.8
