Xy=yz: if you divide each side by y, you get: xy/y=yz/y; so x=z. Since x=z, if you multiply both variables by the same number, they will still equal. Let this number be y: xy=zy. Hope this hels! :)

A rectangle has a length that is five times longer than its width. If the perimeter of the rectangle is 12 inches, what is the w
gulaghasi [49]

Answer:

Width= 1\,inch

Step-by-step explanation:

Length=5\times Width ,  i.e

L=5W

Perimeter=12\,inches

Perimeter of a rectangle is:

                    2(Length+Width)

12=2(5W+W)\\\\12=2(6W)\\\\\dfrac{12}{2} =6W\\\\6=6W\\\\W=\dfrac{6}{6} \\\\W=1\,inch

Width of the rectangle is: 1\,inch

Length=5\times Width

Length=5\times1\\\\Length=5\,inches

Which statement best describes (3 × 4) × 6 = 3 × (4 × 6)?
Anuta_ua [19.1K]

Answer:

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.
