Answer:

7

Step-by-step explanation:

3x - 8 = 13

3x - 8 + 8 = 13 + 8

3x = 21

3x/3 = 21/3

x = 7

Answer:

x = 7

Step-by-step explanation:

To solve for x you need to isolate the x terms to one side. We have to get rid of the negative 8. To get 0 from -8 we need to add 8. Anything you do to one side you do the other so:

3x- 8 = 13 : Add 8 to both sides.

3x = 21 : Now we have 3x but we only want one. So divide both sides by 3.

x = 7

The domain of u(x) is the set of all real values except 0 and the domain of v(x) is the set of all real values except 2. What
Oksana_A [137]

Using the domain concept, the restrictions on the domain of (u.v)(x) are given by:

A. u(x) ≠ 0 and v(x) ≠ 2.

<h3>What is the domain of a data-set?</h3>

The domain of a data-set is the set that contains all possible input values for the data-set.

To calculate u(x) x v(x) = (u.v)(x), we calculate the values of u and v and then multiply them, hence the restrictions for each have to be considered, which means that statement A is correct.

Summarizing, u cannot be calculated at x = 0, v cannot be calculated at x = 2, hence uv cannot be calculated for either x = 0 and x = 2.

ICE Princess25 [194]
If you would like to know how many pages can Henry write in 8 hours, you can calculate this using the following steps:

5 1/4 = 21/4 pages ... 3 hours
x pages = ? ... 8 hours

21/4 * 8 = 3 * x
21 * 2 = 3 * x
3 * x = 42
x = 42 / 3
x = 14 pages

Henry can write 14 pages of his novel in 8 hours.
