Answer:
x=6
Step-by-step explanation:
To solve this problem,
firstly make x to stand alone
subtract 6 from both sides of the equation
x+6-6=12-6
x= 6
2(7÷10)×1÷3+4÷15=1.4×0.33+0.267
=0.462+0.267
=0.729(0.73)

Step-by-step explanation:
note that f ○ g = f(g(x))
To evaluate substitute x = x³ into f(x)
f(g(x)) = f(x³) = 5x³ - 8
In the same way
g ○ f = g(f(x))
To evaluate substitute x = 5x - 8 into g(x)
g(f(x)) = g(5x - 8) = (5x - 8)³
