Answer:
x = 21
Step-by-step explanation:
Inscribed angle = (3x - 3)°
Intercepted arc measure = 120°
Thus:
(3x - 3)° = ½(120°) => an inscribed angle of any circle = ½ the measure of its intercepted arc.
Multiply both sides by 2
2(3x - 3) = 120
6x - 6 = 120
6x - 6 + 6 = 120 + 6
6x = 126
6x/6 = 126/6
x = 21

Answer:
x = 4
Step-by-step explanation:
2.25x=1.5x+6
divide on both sides by 1.5x which equals
1.5x=6
divide both sides by 1.5
x=4
8x - 2x(x+1) = 2(3x-1)
First, expand to remove parenthesis. / Your problem should look like:
8x - 2x - 2 = 6x - 2
Second, subtract 8x - 2x -2 to get 6x - 2. / Your problem should look like:
6x - 2 = 6x - 2
Third, both sides are equal, so there are infinite solutions. The equation is always true, meaning identity
Answer: Infinite solutions
