Answer:
9 sides
Step-by-step explanation:
7y + 2y = 180
9y = 180
y =20
so, 2y, the exterior angle is 2 x 20 = 40
Divide 360 by 40 = 9
Do 21 divided by 2 and you’ll get 10.5 so the original price was $10 and 50 cents
Answer:
10. 108
11. 1,100
<em><u>12.</u></em>
-11 + 13 = 2
35 + -5 = 30
6 + (-3) +4 + 6 + (-5) = 8
5 + (-4) + (-9) + 8 = 0
(6) (8) = 48
(-2) (9) = -18
(-11) (-4) = 44
-256 divided by 0 = 0
-96 divided by +3 = -32
-36 divided by 3 = -12
