Answer:
x = 113°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 6 , then
sum = 180° × 4 = 720°
sum the given angles and equate to 720°
97° + 146° + 134° + 103° + 127° + x = 720°
607° + x = 720° ( subtract 607° from both sides )
x = 113°

Answer:
I believe the answer is D; 5/20+(-12/20).
Step-by-step explanation:
1/4-3/5
5/20-12/20
-7/20
5/20+(-12/20)
5/20-12/20
-7/20
Hope this helps! :D
In the student's equation, there are many problems. Nickels are worth 5 cents, represented by .05, not 50 dollars. Also, the coeffient 5 should not be placed there, it belongs with 5(.1), as we already know how many dimes there are. If we were able to make a new one, it would be, 5(.1)+.05n=1.20.
