after you remove parentheses you do those steps
<em><u>Answer:</u></em>
<h2><em><u>
A is the answer.</u></em></h2>
Step-by-step explanation:
The commutative property changes the numbers in the equation they give. This is very different from identity, distibutive(needs parenthesis), or associative properties.
The value of
that satisfies all the expressions of the system of linear equations is 20.
<h3 /><h3>Procedure - Determination of a variable associated to a pair of corresponding angles</h3>
According to the figure, angles 1 and 5 are <em>corresponding</em> angles between two <em>parallel</em> lines, therefore we have the following equivalence:
(1)
After some algebraic handling we find the value of
:


The value of
that satisfies all the expressions of the system of linear equations is 20.
<h3>Remarks</h3>
There is a missing figure for the statement, we proceed to include it below after some research.
