<h2>Solving Equations with Absolute Values</h2><h3>Answer:</h3>

x = 7 and x = -1

<h3>Step-by-step explanation:</h3>

Solving for the Positive Absolute Value:

|x -3| = 4 \\ x -3 = 4 \\ x -3 +3 = 4 +3 \\ x = 7

Solving for the Negative Absolute Value:

|x -3| = 4 \\ -(x -3) = 4 \\ -(x -3) \cdot -1 = 4 \cdot -1 \\ x -3 = -4 \\ x -3 +3 = -4 +3 \\ x = -1

One expression is the sum of 14 and some number. A second expression is 20. The two expressions are equal. Write an equation and
Stella [2.4K]

Answer:

The answer is 6.

Step-by-step explanation:

Let's say that some number apart of the first expression is the variable x.

The problem says that both expressions are equal so we can set them equal hence an equation.

Equation: 14 + x = 20

As we have set the two expressions that are equivalent to each other (as said so in the problem), our next goal is to solve for the unkown number. To get our unkown number or in other words the number that is the solution for the equation, we subtract 14 from both sides. 20-14 is equal to 6. Now we know that x is 6 so the solution for the equation consisting of the 2 equal expressions is not 2, 5, or 10, but 6.

A salesperson had the following sales: $15.50, $18.98, s16.8, $14, $18.50, and $22. What was the average sale?
Jlenok [28]

Answer:

$ 17.63

Step-by-step explanation:

Given,

The sales of the salesperson are,

$15.50, $18.98, $16.8, $14, $18.50, and $22,

Sum of sales = 15.50 + 18.98 + 16.8 + 14  + 18.50 + 22 = 105.78

Also, the number of sales = 6,

Thus, the average sale = \frac{\text{Sum of sales}}{\text{Number of sales}}

=\frac{105.78}{6}

= $ 17.63
