Equality Properties

Step-by-step explanation:

<u>Step 1: Define Inequality</u>

3x + 1 < 10

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract 1 on both sides:                    3x < 9
  2. Divide 3 on both sides:                       x < 3

Here we see that any value <em>x</em> smaller than 3 would work as a solution to the inequality.

Three orders are placed at a pizza shop. two small pizzas, a liter of soda, and a salad cost $14; one small pizza, a liter of so
mojhsa [17]
To determine the cost of each item, we need to set up equations. From the problem statement, we have three unknowns so we need three equations. We set up equations as follows:

let x cost of small pizzas
     y cost of soda
     z cost of salad
 
two small pizzas, a liter of soda, and a salad cost $14
2x + y + z = 14

one small pizza, a liter of soda, and three salads cost $15

x + y + 3z = 15

three small pizzas, a liter of soda, and two salads cost $22
3x + y + 2z = 22

Solving for x, y and z, we will have:

x = $ 5
y = $ 1
z = $ 3
