Step-by-step explanation:

How to check a solution: Just as you can check the solution to an equation, you can check a solution to an inequality. First, you check the end point by substituting it in the related equation. Then you check to see if the inequality is correct by substituting any other solution to see if it is one of the solutions.

How to tell if its true or false: An inequality is a statement that shows the relationship between two (or more) expressions with one of the following five signs: <, ≤, >, ≥, ≠. Like an equation, an inequality can be true or false. 34 - 12 > 5 + 2 is a true statement. 1 + 3 < 6 - 2 is a false statement.

Archy [21]

Answer:

8 pictures

Step-by-step explanation:

Given

$Window = 5\frac{3}{4}ft$

$Wall = 9.75ft$

$Pictures = 6\ inches$

Required

Determine the number of pictures

First, we need to calculate the length of the available space

This is calculated by subtracting the width of the window from the width of the wall.

$Space = Wall - Window$

$Space = 9.75 - 5\frac{3}{4}$

Convert fraction to decimal

$Space = 9.75 - 5.75$

$Space = 4ft$

Since, the pictures are placed side by side.

This means that, there's no empty space between them.

Number of pictures is:

$Number = \frac{Space}{Pictures}$

$Number = \frac{4\ ft}{6\ in}$

Convert feet to inches

$Number = \frac{4 * 12\ in}{6\ in}$

$Number = \frac{48\ in}{6\ in}$

$Number = \frac{48}{6}$

$Number = 8$

<em>Hence, 8 pictures can fit the wall</em>
