Answer:
x=-4/3
Step-by-step explanation:
3x-12=12x
3x-12x=12
-9/-3=12/-3
then -3 cancels
3x/3=-4/3
then 3 cancels 3
so x=-4/3
Answer:
Step-by-step explanation:
23(9x-6) = 4x +10
207x - 138 = 4x +10
203x = 148
x = 148/203
or
3(9x-6) = 4x +10
27x -18 = 4x + 10
27x - 4x = 10 + 18
23x = 28
x= 28/23
Answer:
40°
Step-by-step explanation:
Measure of Nonagon (9-sided polygon) = 1260°
