Step-by-step explanation:
i think its 6
The equation is A
explanation:
The smallest angle would be 19 degrees. So option D is correct.
<h3>What is the sum of the octagon?</h3>
The sum of exterior angles of the regular octagon is 360 degrees.
Given;
The angles
x + 13 + 2x - 1 + 2x + 6 + 2x + 12 + 2x - 17 + 3x - 4 + 3x - 10 + 4x = 360
19x - 1 = 360
19x = 359
x = 18.89
The smallest angle would be
2x - 17 = 2(18.89) - 17 = 19

Answer:
Step-by-step explanation:
BASE + 3x = 22.85.....................equation 1
BASE + 10x = 40..........................equation 2
BASE = 40 - 10x
NOW SUBSTITUTE (40-10x) FOR BASE IN THE FIRST EQUATION
40 - 10x + 3x = 22.85
-7x = 22.85 - 40
-7x = -17.15
x = -17.15/-7
x = $2.45 IS THE PRICE FOR EACH POUND.
BASE + 10 x 2.45=40
BASE + 24.50=40
BASE = 40-24.50
BASE = 15.50 IS THE BASE PRICE FOR THE DELIVERY.
PROOF
15.50+3*2.45=22.85
15.50+7.35=22.85
22.85=22.85
