Korea’s median age in years, 43.7 is 22.3 less than 3 times the number of days Dr. E. Quation has spent in police custody for attempted crimes. How many days has the doctor spent in police custody? *

The doctor spent 22 days in police custody

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The number of days Dr. E. Quation has spent in police custody will be the variable x. We have to multiply it  by 3 (3times) and subtract 22.3.

That expression must be equal to Korea’s median age in years (43.7)

Mathematically speaking;

43.7 = 3x-22.3

Solving for x:

43.7+22.3 =3x

66 = 3x

66/3 =x

22=x

The doctor spent 22 days in police custody

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

answer: its the third option.
