Answer 1

Answer:

All properties that were used to simplify the following problem:

1. commutative property of multiplication

2. multiplicative inverse 3. multiplicative identity

What is commutative property of addition?

The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.

For two numbers x and y, we have: x + y = y + x

Thus, if we take 3 numbers as a,b and c;

a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a

We have been given an expression;

2/7 • 53 • 7/2

53 • 2/7 • 7/2

53 • 1

53

Then all properties that were used to simplify the following problem:

1. commutative property of multiplication

2. multiplicative inverse

3. multiplicative identity

A rectangular garden has a width of 67 inches and a length of 92 inches. What is the perimeter of the garden in feet? Group of answer choices 31.8 feet 26.5 feet 13.25 feet 42.8 feet

Answers

The answer is 13.25
67+92= 159
159 divided by 12= 13.25

The perimeter of the garden is approximately 26.5 feet according to given question.

To calculate the perimeter of the rectangular garden, we need to add up the lengths of all four sides.

Given:

Width of the garden = 67 inches

Length of the garden = 92 inches

The formula for calculating the perimeter of a rectangle is:

Perimeter = 2 * (Width + Length)

Plugging in the given values, we have:

Perimeter = 2 * (67 inches + 92 inches)

Perimeter = 2 * 159 inches

Perimeter = 318 inches

To convert the perimeter from inches to feet, we divide by 12 since there are 12 inches in a foot:

Perimeter = 318 inches / 12 inches/foot

Perimeter ≈ 26.5 feet

Therefore, the perimeter of the garden is approximately 26.5 feet.
