Front

What is the process for solving for a variable in an equation?

Back

1. Isolate the variable on one side of the equation. 2. Perform inverse operations to both sides to maintain equality. 3. Simplify the equation to find the value of the variable.

How do you round a number to the nearest tenth?

Back

1. Identify the tenths place (first digit to the right of the decimal). 2. Look at the digit to the right of the tenths place. 3. If it's 5 or more, round up; if it's less than 5, round down.

Front

What does it mean to express an answer without spaces?

Back

It means to write the answer in a continuous format without any spaces between the variable and its value, e.g., x=23.2.

Front

What is the value of x if x=23.2 or x=23.3?

Back

x can be either 23.2 or 23.3, depending on the context of the problem.

Front

If y=17.1, what is the value of y rounded to the nearest tenth?

Back

y=17.1 is already rounded to the nearest tenth.

Front

What is the significance of rounding in mathematical problems?

Back

Rounding helps simplify numbers for easier interpretation and calculation, especially in real-world applications.

Front

How do you determine the correct answer when multiple options are provided?

Back

Evaluate each option based on the problem's requirements and select the one that meets the criteria.

Front

What is the importance of showing work in solving equations?

Back

Showing work helps to track the steps taken, allows for easier identification of errors, and demonstrates understanding of the process.

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 isolate a variable?

Back

To isolate a variable means to manipulate the equation so that the variable is on one side by itself, making it easier to solve.
