Solve the equation. Round to the nearest thousandth. -12e-x + 8 = 7

Marysya12 [62]

Answer:

-12e-x + 8 = 7

-12e-x = 7-8

-12e-x = -1

12e-x = 1

e-x = 1/12

ln(e-x) = ln(1/12)

x = -ln(1/12)

x = -2.485

aniked [119]

Answer:

Step-by-step explanation:

Answer:

Elena's running speed is 5 miles/hour

Explanation:

The speed is defined as the covered distance per unit time

In the problem, we have:

The distance covered is the length (circumference) of the circular track which is given as of a mile.

We are also given that she completes each lap (she completes of a mile) in of an hour

To get her speed, we will divide the distance covered by the time taken to cover this distance

This is done as follows:

speed = miles/hour

This means that:

Elena can run 5 miles each hour

Hope this helps :)
