Which equations illustrate the commutative property of multiplication?
choose exactly two answers that are correct.
a.
-1/2 • 3.4 = 3.4 • (-1/2)
b.
–8 • (5 + 3.1) = (5 + 3.1) • (–8)
c.
–4 • (5 + 7.1) = –4 • 5 + (–4) • 7.1
d.
–8 • (4 • 1) = (–8 • 4) • 1
Option A. 12 + 6 + 15 = 12 + 15 + 6
Step-by-step explanation:
Cumulative property of addition says if there are three numbers a, b, c then
a + b + c = a + c + b
or a + b + c = c + b + a
Therefore, if three numbers are 12, 6, 15 then
equation that illustrates the commutative property of addition will be
12 + 6 + 15 = 12 + 15 + 6
Option A. 12 + 6 + 15 = 12 + 15 + 6 will be the correct option.
12 + 6 + 15 = 12 + 15 + 6
Hope this helps 😀
The answer is B AND D
Step-by-step explanation:
A. ab = ba beacause commutative means change in order of equation. all of them stay the same except A
12+6+15=12+15+6 would be correct because the communitive property states that the order can be switched but will still have the same answer
12 + 6 + 15 = 12 + 15 + 6
This is the answer because its the same even though it switches the order around.
(Wrong category btw)
Hope this helps!~
The answer is A.
Answer choices B, C, and D all show the associative property.
C)[tex]2 + b = b + 2[/tex]
Step-by-step explanation:
We are supposed to find which equations illustrates the commutative property.
Commutative property : The "Commutative Laws" say we can swap numbers over and still get the same answer i.e.
[tex]a+b=b+a[/tex]
Substitute a =2
So, [tex]2+b=b+2[/tex]
So, Option C satisfies the law
Option A , B and D does not satisfies the law .
Only Option C is true .
[tex]2 + b = b + 2[/tex]
12+6+15=12+6+15 is the correct answer
2 + b = b + 2
Step-by-step explanation:
Commutative property states that
a+b = b+a
changing the order of terms will not affect the equation
8 + 3 = 4 + 7
Here the order is not changed, the numbers are changed
So the above equation does not illustrates commutative property
If 3 + 5 = a, then a = 3 + 5
3+5 = 3+5, here the order is not changed
the above equation does not illustrates commutative property
2 + b = b + 2
Here the order of terms are changed. It does not affects the equation
the above equation illustrates commutative property
3(2 + 5) = 6 + 15
In this equation the distributive property is used
3 is distributed inside the parenthesis
the above equation does not illustrates commutative property
