The question is incomplete. Here is the complete question.

A 50 gram sample of a substance that's used to treat thyroid disorders has a k-value of 0.1137. Find the substance's half-life, in days. Round your answer to the nearest tenth.

= 6.1 days

Step-by-step explanation: Half-life is the amount of time necessary for a substance to reduce to half of its initial value.

To determine half-life through mass of a substance:

Initially, there are 50 grams. After 1 half-life, there are 25 grams:

ln(1) - ln(2) = -0.1137.

6.1

The half-life of the sample substance is 6.1 days.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
