Answer:
Commutative
Step-by-step explanation:
There are four basic property of operations to solve an algebraic expressions. They are associative, commutative, distributive and identity.
The expression given is :
So the given algebraic expression is a commutative property of operations. The commutative property states that when any two numbers are added in an expression the sum of the numbers are the same regardless of the order of the numbers that are added.
Thus the sum of the above expression will be same in which ever order the numbers are added.
4/8 ÷ 6/8
= 4/8 × 8/6
= 4/6
=2/3
Answer:
The two equations are not equivalent and no property is used.
Step-by-step explanation:
54 - (30 - 8) ... (i)
(54 - 30) - 8 ... (ii)
Solving (i) and applying PEMDAS:
We open the brackets first;
54 - 30 + 8 = 54 + 8 - 30 = 32
Solving (ii) and applying PEMDAS:
We open the brackets first;
54 - 30 = 24
24 - 8 = 16
1 and 5 - corresponding
2 and 7 - consecutive interior
3 and 5 - none
3 and 8 - alternate exterior
4 and 7 - alternate interior
4 and 8 - none

Shown below
<h2>
Step-by-step explanation:</h2>
The first system of inequality is the following:
To find the solution here, let's take one point, say, and let's taste this point into both inequalities, so:
<h3>FIRST CASE:</h3>
First inequality:
The region is not the one where the point lies
Second inequality:
The region is the one where the point lies
So the solution in this first case has been plotted in the first figure. As you can see, there is no any solution there
<h3>SECOND CASE:</h3>
First inequality:
The region is the one where the point lies
Second inequality:
The region is not the one where the point lies
So the solution in this first case has been plotted in the second figure. As you can see, there is a solution there.
CONCLUSION: Notice that when reversing the signs on both inequalities the solution in the second case is the part of the plane where the first case didn't find shaded region.
