Solve this equation for x. Round your answer to<br> the nearest hundredth.<br> 3 = In(x + 9)

Mrac [35]

Answer:

x ≈ 11.09

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n ⇒ x = $b^{n}$

Given

ln(x + 9) = 3 , that is

$log_{e}$ (x + 9) = 3 , then

x + 9 = e³ ( subtract 9 from both sides )

x = e³ - 9 ≈ 11.09 ( to the nearest hundredth )

John runs every day. The number of miles that he runs varies per day. Write a variable expression to show John's total miles for

Alekssandra [29.7K]

In this item, we are given that the number of miles that John runs every day vary. Therefore, it is just rightful that we use three different variables for the number of miles he ran for three days. For the purpose of representation in this item, we let the variables be x, y, and z. The total miles he ran is equal to the sum of the three variables. Let T be the total and that would be equal to,

<em> T = x + y + z</em>
