Back

m = 5 + n

Front

What is an inequality?

Back

An inequality is a mathematical statement that indicates one quantity is larger or smaller than another, using symbols like >, <, ≥, or ≤.

Front

What does the symbol '≥' mean in an inequality?

Back

The symbol '≥' means 'greater than or equal to'.

Front

What is the purpose of solving equations?

Back

The purpose of solving equations is to find the value of the variable that makes the equation true.

Front

What is the first step in solving the equation 2w + 2b = P?

Back

The first step is to isolate the term with the variable, which can be done by subtracting 2b from both sides.

Front

What does 'p' represent in the ideal gas law pV = nRT?

Back
