Explanation: For this, we take two different numbers.

Let the first number be x and the second number be y

We use the commutative property, which says that the sum will remain same in whatever way the numbers are written.

Mathematically,

x+y=y+x

From the question,

x = 1

y = 7

Putting this in the commutative property equation, we get:

1+7=7+1

Hence, the sum of both the umber will be same.

sattari [20]

Answer:

The inequality to determine how many hours Ms. Vicker must tutor to have enough money for the dress.

$600 + 10x ≥ $1200

Step-by-step explanation:

From the question, we are told that:

Ms. Vicker is trying to save enough money to buy her wedding dress at the cost of $1,200. She has $600 saved from her summer school job.

The amount to make up to complete her wedding dress = $1200 - $600

= $600

To make the rest of the money, Ms. Vicker plans to tutor for Sylvan at a cost of $10 per hour.

= Number of hours Ms vicker must tutor Sylvan to make $600 is calculated as:

$600/$10 = 60 hours

The inequality to determine how many hours Ms. Vicker must tutor to have enough money for the dress is written as

$600 + 10x ≥ $1200
