<u>Given</u>:

Four lines are marked proportion, the length of TW can be determined by

TW=a+4+b

<u>Value of a:</u>

Let us set the proportion for the given lines.

Thus, we have;

 \frac{a}{7}=\frac{4}{5}

5a=28

 a=5.6

Thus, the value of a is 5.6

<u>Value of b:</u>

Let us set the proportion for the given lines.

Thus, we have;

 \frac{4}{5}=\frac{b}{5}

20=5b

 4=b

Thus, the value of b is 5.

<u>Length of TW:</u>

The length of TW is given by

TW=5.6+4+4

TW=13.6

Thus, the length of TW is 13.6

Which number line represents the solution set for the inequality 3(8 – 4x) &lt; 6(x – 5)?
MrMuchimi

The solution to the inequality is x > 3

The number line that represent the solution set will be:

<em>A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right</em>. The correct option is the second option

<h3>Linear Inequalities </h3>

From the question, we are to determine the number line that represents the solution set for the given inequality

The given inequality is

3(8 – 4x) < 6(x – 5)

First, we will solve the inequality

3(8 – 4x) < 6(x – 5)

Clear the brackets

24 - 12x < 6x - 30

Collect like terms

24 + 30 < 6x + 12x

54 < 18x

Divide both sides by 18

3 < x

∴ x > 3

Hence, the number line that represent the solution set will be:

<em>A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right</em>. The correct option is the second option
