6n - 13 = 27
6n = 27 + 13
6n = 40
n = 40/6
n = 6 2/3
Answer: n = 6 2/3
Answer:
1. 144⁰
2. 60⁰
Step-by-step explanation:
The formula to find the measure of the interior angles of a regular polygon is:
m< = (n - 2) • 180/n where n = the number of sides
For a decagon, there are 10 sides.
m< = (10-2) • 180/10 = 144°
A regular polygon/equilateral triangle is defined as having equal sides and angles.
Answer:
Step-by-step explanation:
11x+11
or you could do
11(x+1)
Answer:
12 sandwiches
Step-by-step explanation:
If 3 sandwiches cost $20
Then x sandwiches cost $80
3----20
x----80
20x=3 x 80
20x=240
x=240/20
x=12 sandwiches
When there are one positive and one negative
