Which pair of expressions is equivalent using the Associative Property of Multiplication? (3 points) 5(3a ⋅ 4) = 15a ⋅ 20 5(3a ⋅

cluponka [151]

Answer:

5(3a ⋅ 4) = (5 ⋅ 3a) ⋅ 4

Step-by-step explanation:

The Associative Property is applied to two types of operations: addition and multiplication. This property indicates that, when there are three or more terms in these operations, the result does not depend on the way in which the terms are grouped.

In this sense, the associative property for the sum is mathematically given by:

$(x+y)+z=x+(y+z)$

and for the multiplication by:

$(xy)z=x(yz)$

Now, let:

$x=5\\y=3a\\z=4$

Using the Associative Property of Multiplication:

$(xy)z=x(yz)\\\\Replacing\hspace{3}the\hspace{3}values\\\\(5\cdot 3a)\cdot4=5(3a\cdot 4)$

Therefore the equivalent expressions are:

5(3a ⋅ 4) = (5 ⋅ 3a) ⋅ 4

The _______ are all the counting numbers.

Bingel [31]

It cannot be be Integers because Integers include negative numbers (which are not counting numbers)

It cannot be real numbers because like integers, it includes negative numbers but also includes decimals which are not counting numbers

It cannot be absolute values because absolute values is the range of how far away a number is from 0 which obviously isn't counting

That leaves natural numbers which are counted in sequence which fits the definition needed

Answer: D. Natural Numbers
