Absolute value represents a value's distance from <u>zero (0)</u> on the number line. It is expressed using a pair of <u>vertical</u> bars. In the order of operations, absolute value signs are considered like <u>parenthesis</u> and other grouping symbols. We complete the operations inside the absolute value signs <u>first</u> to get a single number. Then we take the absolute value of the number at the same time we evaluate <u>exponents</u> in the expression.
<h3>What is a number line?</h3>
A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numerical values (numbers) that are placed at equal intervals along its length.
<h3>What is an absolute value function?</h3>
An absolute value function can be defined as a type of function that consist of an algebraic expression, which placed within absolute value symbols.
<h3>The equation of an absolute value function.</h3>
Mathematically, the standard form of the equation for an absolute value function is given by:
y = a|x - h| +k.
Where:
h and k are the vertex of the graph.
<h3>The characteristics of an absolute value.</h3>
Absolute value represents a value's distance from <u>zero (0)</u> on the number line. Also, it is typically expressed using a pair of <u>vertical</u> bars. In the order of operations, absolute value signs are considered like <u>parenthesis</u> and other grouping symbols such as brackets.
Furthermore, you should complete the operations inside the absolute value signs <u>first</u> to get a single number. Then, you take the absolute value of the number at the same time when you evaluate <u>exponents</u> in the expression.

Total amount = $520
Sharing Ratio = 2 : 4 : 7
First Student Ratio : 2
Second Student Ratio : 4
Third Student Ratio : 7
Total Quantities of ratio = 2 + 4 + 7 = 13
<u>Formula</u><u> </u><u>applied</u><u> </u><u>:</u><u> </u>
Share = Ratio of Student / Total quantities of ratio × Total amount
First Student share :
= 2/13 × 520
= $80
Second student share:
= 4/13 × 520
= $160
Third Student share :
= 7/13 × 520
= $280 .
Proof :
Total share = $520
( 80 + 160 + 280 )= $520
$520 = $520
You should add the total of the females together. So 4+11+16+2 which is 33. Then 16/33.
