Answer:
100
Step-by-step explanation:
To find mean/average you add all of them together, then divide by however number there are.
So
99+88+97+107+100+109 = 600/6 = 100
Answer:
m<R = 65
Step-by-step explanation:
m<R + m<S + m<T = 180° (sum of interior angles in a triangle)
(5x - 11) + (3x - 3) + (3x + 18) = 180°
Solve for x.
5x - 11 + 3x - 3 + 3x + 18 = 180
Add like terms
11x + 4 = 180
11x = 180 - 4
11x = 176
x = 16
m<R = (5x - 11)
Plug in the value of x
m<R = 5(13) - 11
m<R = 65
Answer:
2=2=2=2=2=2=2=2=2=2=2=2=2=2=2
Step-by-step explanation:
Answer:
C /2pi = r
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi*r
We want to solve for r
Divide each side by 2 pi
C / 2pi = 2*pi*r / 2pi
C /2pi = r
Let the unknown number be x.
6x + 8 = 9x
-3x = -8
x = 8/3
The number is 8/3 or 2 2/3
