To find a number between both decimals, what you can do is take the average of both numbers.

We have then:

average = \frac{0.4+0.5}{2}

Rewriting we have:

average = \frac{0.9}{2} \\average = 0.45

Therefore, the decimal obtained is a number between 0.4 and 0.5

Answer:

a decimal between 0.4 and 0.5 is:

average = 0.45

Help please!!!!!:( Solve the equation for x. Round your answer to two decimal places. Do not include "x =" in your answer.
svet-max [94.6K]
The solution to the problem is as follows:

If you use Ln you can get rid of e. 

ln(e^0.4x) = ln(0.4) 

0.4x = ln(0.4) 

x = (ln(0.4))/0.4 

<span>x = -2.29
