Answer:
mean= 90
Step-by-step explanation:
The mean is the terms added together, then divided by the number of terms (in this case, 8):
Done.
Answer:
vertex angle = 180° - 2x
Step-by-step explanation:
Since, the measure of each base angle of an isosceles triangle is represented by x.
So, by interior angle sum postulate of a triangle, we have:
x + x + vertex angle = 180°
2x + vertex angle = 180°
vertex angle = 180° - 2x
So, the vertex angle is represented by (180° - 2x).
Y+7= -(2/3)x+6)
First distribute the -1.
y+7= -(2/3)x-6
Then subtract 7 from both sides to isolate y.
y= -(2/3)x-13
Final answer: f(x)= -(2/3)x-13
Step-by-step explanation:
4+5/6*3/10
29/6*3/10
=87/60
=29/20
=1 9/20
