9x +1= 0
9x/9 +1-1=0
X= 9-1
X= 8
it is a polygon and it would be a decagon since there are 10 sides
Answer: 77-p
Step-by-step explanation:
o=other number
o+p=77
o+p-p=77-p
o=77-p
30x - 20 = 50
use inverse operations to isolate x
30x - 20 = 50
+ 20 +20
30x = 70
(30x = 70) /30
x= 7/3 (this is the simplified term)
