Answer:
the sum of consecutive prime numbers: 11 + 13 = 24
hope this is right
80 x 3/10 = 240/10 = 24 times
The geometric mean you would use is C
The answer is x <span> ≤ 6, i think</span>
Answer:
7 of the angles measure 144 degrees each and one angle measures 72 degrees
Step-by-step explanation:
Let
x -----> represent the measures of the seven same-size angles,
x/2 ----> represent the measure of the one that is "two times smaller."
we know that
The sum of internal angles of a polygon can be calculated as:

where
n is the number of sides of the polygon
In this case
n=8 (octagon)
substitute

so
The linear equation that represent this problem is

solve for x

so

therefore
7 of the angles measure 144 degrees each and one angle measures 72 degrees
