X ÷ 9 = 6
Multiply both sides by 9
x ÷ 9 • 9 = 6 • 9
x = 54
-18 negative eighteen
6 positive six
12 positive twelve
-40 negative forty
Answer:
Step-by-step explanation:
Rate = 56 gal / 7 min
= 8 gal / min
The formula for the total sum of the inner angles of the polygon is
Sn= (n-2) 180°
1) S6= (6-2) 180 = 4*180 = 720° In the hexagon all angles are equal
α= S6/6= 720/6= 120°
2) In each polygon the sum of the external angles is 360°
3) S5= (5-2) 180 = 540° than we can add up all angles
x+131+108+107+110=540 => x= 540-456= 84°
4) α = 360/5=72°
Good luck!!!
