What is an equation?

Back

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

Front

What does the variable 'N' represent in the equation 4 + N = 8?

Back

The variable 'N' represents a number that, when added to 4, equals 8. In this case, N = 4.

Front

How do you solve for a variable in an equation?

Back

To solve for a variable, isolate it on one side of the equation using inverse operations.

Front

What is the solution to the equation 14 - Z = 5?

Back

Z = 9, because when you subtract 9 from 14, you get 5.

Front

Write an equation for the total number of students on a field trip if 4 students rode in cars and the rest filled 9 buses with x students each.

Back

The equation is 4 + 9x = 472.

Front

What does 'x' represent in the equation 4 + 9x = 472?

Back

In this equation, 'x' represents the number of students in each bus.

Front

How do you write an equation for a total cost?

Back

To write an equation for total cost, sum the costs of individual items, often represented as variables.

Front

What is the equation for the total cost if Ms. Connolly bought 4 watermelons at $x each and a cantaloupe for $3?

Back

The equation is 4x + 3.

Front

What does 'R' represent in the equation R x 4 = 16?

Back

'R' represents a number that, when multiplied by 4, equals 16. In this case, R = 4.

Front

What is the first step to solve the equation R x 4 = 16?

Back

Divide both sides of the equation by 4 to isolate R.
