Answer:
I think it's 1/16
Step-by-step explanation:
0.50x-6=4
move -6 to the other side
sign changes from -6 to 6
0.50x-6+6= 4+6
0.50x= 10
divide by 0.50 for both sides
0.50/0.50x= 10/0.50
x= 20
Answer: x= 20

Answer:
Step-by-step explanation:
The interior angles of a heptagon add up to 5*180 = 900
So
x + 143 + 116 + 135 + 135 + 116 + 155 = 900 Add up the known angles
x + 800 = 900 Subtract 800 from both sides
x + 800 - 800 = 900 - 800 Combine
x = 100
