Which statement best describes (3 × 4) × 6 = 3 × (4 × 6)?

This is the associative property.

Step-by-step explanation:

The only operation in this expression is multiplication.

We know that the order in which we multiply numbers does not change their product; therefore we can group different numbers together and get the same product.

In this case, on the right hand side, 3 and 4 are grouped together first, then multiplied by 6.  This gives us 12*6 = 72.

On the left hand side, 4 and 6 are grouped together first, then multiplied by 3. This gives us 24*3 = 72.

x/3-10=8

x/3=18

x=48
