Question

What is the solution to the equation below? Round your answer to two

decimal places.
4 + 9•In x= 15.8
A. x = 3.56
B. x= 0.27
C. x = 3.71
D. x = 2.09

Answer 1

4 + 9 • In x = 15.8

x= 3.71

Answer 2

C. x = 3.71

Explanation:

4 + 9(ln x) = 15.8

Subtract 4 from both sides.

9(ln x) = 11.8

Divide both sides by 9.

ln x = 11.8/9

x = e^(11.8/9)

x = 3.71
