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

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
