Answer:

The answer is A.

Step-by-step explanation:

Lets call f(x)=y, so y= 4*(3*x-5), we want to find 'x', using 'y' as a the variable.

y=12x-20\\ y+20=12x\\ x=\frac{y+20}{12}

Now lets change the name of 'y' to 'x', and 'x' to f^-1(x).

f-1(x) = (x+20)/12

nignag [31]

Answer:

1. 247 mg ÷ 10 = 24.7 cg

2. 247 mg ÷ 100 = 2.47 dg

247 mg ÷ 1000 = 0.247 g

Step-by-step explanation:

1. To convert from 'mg' to 'cg', you must divide by 10 because 'cg' consists of 10 mg.

2. To convert from 'mg' to 'dg', you must divide by 100 because 'dg' consists of 100 mg.

3. To convert from 'mg' to 'g', you must divide by 1000 because 'g' consists of 1000 mg.
