Answer 2

An algebriac expression for the given word phrase is given by: A. 3x/2.

How to write an algebriac expression?

In this exercise, you're required to write an algebriac expression for the given word phrase. Thus, we would translate it as follows:

The product of x and 3 is (x × 3).

Half of the above is given by:

1/2 × (x × 3) = 3x/2.

How to simplify an algebriac expression?

The first mathematical operation to be done when solving an algebriac expression is to open up the bracket as follows:

(5x/9 + 3) + 7 = 5x/9 + 3 + 7

5x/9 + 3 + 7 = 5x/9 + 10.

The perimeter of a rectangle.

Mathematically, the perimeter of a rectangle is calculated by using this formula;

P = 2(L + W)

P = 2(x - 3 + 2x + 1)

P = 2(3x - 2)

P = 6x - 4.

How to solve for x?

In order to find an equivalent equation, we would make x the subject of formula in the given equation:

3x - 9y = 24

3x = 9y + 24

Dividing both sides by 3, we have:

x = 3y + 8.

The associative property of addition.

(5x + 2) - 9 = 5x + (2 - 9)

5x + 2 - 9 = 5x + 2 - 9

5x - 7 = 5x - 7.

Therefore, the equation represents an associative property of addition because the sum remains the same regardless of how they're arranged.
