<h2>
Forming Equations from Word Problems</h2>
To form equations from word problems, we can derive mathematical operations as well as variables from the given information.
In this case, each time Walker reads a certain number of pages, we subtract that from the total number of pages left to know how many pages is left to read.
<h2>Solving the Question</h2>
<em>Let r represent the pages left to read.</em>
<em />
792 pages in total
Walker reads 15 pages a day during the week and 25 pages a day during the weekend.
- There are 5 weekdays, and he reads 15 pages each of those days. ⇒ <em>r</em> = 792 - 5×15
- There are 2 weekend days, and he reads 25 pages each of those days.
⇒ <em>r</em> = 792 - (5×15 + 2×25)
5 weeks have passed
- Multiply the terms representing the number of pages he reads a week by 5, for 5 weeks.
⇒ <em>r</em> = 792 - (5×15 + 2×25)×5
<h2>Answer</h2>
<em>r</em> = 792 - (5×15 + 2×25)×5

Answer:
Inequality Form: -5 < x < 2
Step-by-step explanation:
Move all terms not containing x from the center section of the inequality.
Inequality Form: -5 < x < 2
Interval notation: (-5,2)
The answer to this specific formula is 2
The value of the expression (-4x - 4) + (-4x - 10) is -8x - 14
<h3>What are expressions?</h3>
Expressions are mathematical statements that are represented by variables, coefficients and operators
<h3>How to determine the value of the expression?</h3>
The expression is given as
The sum of (-4x - 4) and (-4x - 10)
This can be represented as
(-4x - 4) + (-4x - 10)
Remove the bracket
So, we have
(-4x - 4) + (-4x - 10) = -4x - 4 - 4x - 10
Collect the like terms
So, we have
(-4x - 4) + (-4x - 10) = -4x - 4x - 4 - 10
Evaluate the like terms
So, we have
(-4x - 4) + (-4x - 10) = -8x - 14
Hence, the value of the expression (-4x - 4) + (-4x - 10) is -8x - 14
