Lesson Steps

Step Type Explanation Answer

1

Problem

Use the Associative Property of Multiplication to find the value of a variable
\$ 2 \times (4 \times x) = (2 \times 4) \times 3 \$.

2

Step

The given equation

\$ 2 \times (4 \times x) = (2 \times 4) \times 3 \$

3

Formula:

Associative property of multiplication

\$ a times (b times c) = (a times b) times c \$

4

Hint

The Associative Property states that changing the grouping of factors in a multiplication equation does not change the product.

5

Step

Now first simplify the equation on the right side:

\$ (2 \times 4) \times 3 = 8 times 3 = 24 \$

6

Step

Now, let’s equate it to the equation on the left side:

\$ 2 \times (4 \times x) = 24 \$

7

Step

To isolate x, we’ll divide both sides by 2:

\$ 4 \times x = 24/2\$

\$ 4 \times x = 12\$

8

Step

Finally, to find the value of x, we divide both sides by 4:

\$ x = 12/4 \$

\$ x = 3 \$

9

Step

So, the value of the variable x is 3.

10

Choice.A

This is the correct answer. It matches the solution we obtained

3

11

Choice.B

This would require 8 × 44 = 24, which is not true

44

12

Choice.C

This implies that \$4 times x = 24\$, making x = 6, which would lead to a different result than 24 when applied to the left side

24

13

Choice.D

If x = 2, then 2 × (4 × 2) = 2 × 8 = 16, which is not equal to 24
