Beyoncé’s engagement ring from Jay Z is valued at more than $5 million.
What are two possible values for the ring's price?
How can you use a number sentence to represent this amount?
Since the ring's value is “more than $5 million," the possible values must be greater than $5 million. There are many possibilities, but two examples could be $6 million or $5.5 million.
The key phrase is “more than,” requiring the greater than symbol. A number sentence to represent this situation would be r > $5 million.
Write responses to the following questions in your math journal.
How can you determine if you use equal to in your inequality comparison?
Can an equation with an equal sign have more than one solution? Explain.
To determine if you use equal to in your inequality comparison, you need to consider the information given in the problem or situation. If the problem states that the value is "exactly" or "equal to" a certain amount, then you would use the equal sign in your inequality comparison. For example, if the problem said "Beyoncé's engagement ring is valued at $5 million," then you would use the equal sign in your equation.
An equation with an equal sign can have more than one solution, as long as each solution satisfies the equation. For example, the equation 2x = 10 has the solution x = 5, but it also has the solution x = 2.5. Both values of x make the equation true, so they are both valid solutions.
