The number of miles in day at which the rental cost for the company A and Company B are the same is 200 miles

The Company A rented the truck for $40 a day plus $0.40 per miles

The expression will be

40+0.40x

Where x  is the number of miles

The company B rented the truck for $20 a day plus $0.50 per miles

20+0.50x

To find the number of miles in a day at which the rental costs for Company A and Company B are the same, the linear equation will be

40+0.40x = 20+0.50x

40-20 = 0.50x-0.40x

0.1x = 20

x = 200 miles

Hence, the number of miles in day at which the rental cost for the company A and Company B are the same is 200 miles

Your math teacher asked you to solve the equation in the box.
lawyer [7]

Answer:

x = x - 4/6

false

Step-by-step explanation:

6(x - 1) - 4x = 2(3x - 5)

First, lets distribute the 6 to each item inside the parentheses on the left side. You can do this by multiplying the 6 by each term.

6 * x = 6x

6 * -1 = -6

6x - 6 - 4x = 2(3x - 5)

Next, we will combine like terms.

6x - 4x = 2x

2x - 6 = 2(3x - 5)

Now, let's look at the right side of the equation.

Let's distribute the 2 to each item inside the parentheses on the left side. You can do this by multiplying the 2 by each term.

2 * 3x = 6x

2 * -5 = -10

6x - 1 = 6x - 5

Immediately, we can tell this is false, but let's solve the equation just to make sure.

6x - 1 = 6x - 5

+1              +1

6x = 6x - 4

---     --------

6        6

x = x - 4/6

This is false.

Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours. What is the mean absolute deviati
Irina-Kira [14]

The mean absolute deviation for the number of hours students practiced the violin is 6.4.

<h3>What is the mean absolute deviation?</h3>

The average absolute deviation of the collected data set is the average of absolute deviations from a center point of the data set.

Given

Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours.

The given data set is;

45, 38, 52, 58, 42

Mean Deviation = Σ|x − μ|/N.

μ = mean, and N = total number of values

|x − μ| = |45 − 47| = 2

|38− 47| = 9

|52− 47| = 5

|58− 47| = 11

|42− 47| = 5

The mean absolute deviation for the number of hours students practiced the violin is;

\rm Mean =\dfrac{2+9+5+11+5}{5}\\\\Mean=\dfrac{32}{5}\\\\Mean = 6.4

Hence, the mean absolute deviation for the number of hours students practiced the violin is 6.4.
