Answer:
7.6
Step-by-step explanation:
mean = [weights] / amount of weights
m = 10 + 7 + 6 + 10 + 13 + 10 / 6
m = 46 / 6
m = 7.66666666 (recurring)
m = 7.6
Sample Response:
<em>The linear equations have the same slope, so the rate of change for each is the same. As long as the rate of change is the same, the lines will stay the same distance apart and not intersect.</em>

Answer:
7 < x < 34
Step-by-step explanation:
The answer must be greater than 7, else the two sides are less than or equal to the third. That triangle is impossible. The answer must also be less than 34, because then the two other sides would equal the third, making an impossible triangle.

Answer:
The vertex angle = 28 degrees.
Each of the base angles = 76 degrees.
Step-by-step explanation:
The 2 base angles of an isosceles triangle are equal.
The relation between the vertex angle and one of the base angles is as follows:
2x + y = 180 where x = the measure of a base angle and y = the measure of the vertex angle.
Also, from the information given in the question:
x = 3y - 8
so we have the system of equations:
2x + y = 180........(1)
x - 3y = -8...........(2)
Multiply equation (2) by -2:
-2x + 6y = 16......(3)
Adding (1) and (3):
7y = 196
y = 28.
Substituting for y in equation (2):
x - 3(28) = -8
x = -8 + 84
x = 76.
