Creating Equations to solve real life situations

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing variables.

Front

What does it mean to solve an equation?

Back

To solve an equation means to find the value(s) of the variable(s) that make the equation true.

Front

What is a variable in mathematics?

Back

A variable is a symbol, often a letter, that represents an unknown value in an equation.

Front

How do you represent a real-life situation with an equation?

Back

You identify the quantities involved, assign variables to unknowns, and express relationships using mathematical operations.

Front

What is a constant in an equation?

Back

A constant is a fixed value that does not change, such as a specific cost or amount.

Front

How do you isolate a variable in an equation?

Back

You perform inverse operations to both sides of the equation to get the variable alone on one side.

Front

What is the first step in solving a word problem?

Back

The first step is to read the problem carefully and identify the known and unknown quantities.

Front

How do you check if your solution to an equation is correct?

Back

You substitute the solution back into the original equation to see if both sides are equal.

Front

What does it mean to 'pitch in' in a group expense?

Back

To 'pitch in' means to contribute a share of the total cost among all participants.

Front

How can you express a total cost in an equation?

Back

You can express total cost as the sum of fixed costs and variable costs, such as total cost = fixed cost + (variable cost per unit * number of units).
