2. Choose from the following to describe what kind of sentence this is: "It was blue with white stripes."

Explanation

This sentence is an open sentence because it does not provide enough information to determine its type. It simply states a fact about something being blue with white stripes, but it does not express a complete thought or provide any additional context.

Submit
3. Which of the following is an example of an open sentence?

Explanation

An open sentence is a statement that contains one or more variables and becomes a proposition when specific values are substituted for the variables. In the given options, "It is a fraction" is the only statement that contains a variable ("It") and can be true or false depending on the value assigned to the variable. The other options are complete statements that do not contain any variables.

Submit
4. Given the open sentence: 3x - 7 = 11 Which value of x would be in the "solution set?"

Explanation

The correct answer is x = 6 because when we substitute x = 6 into the open sentence 3x - 7 = 11, we get 3(6) - 7 = 18 - 7 = 11, which satisfies the equation.

7. CHECK ALL THAT MAY APPLY to describe the following sentence (COULD BE MORE THAN ONE ANSWER) "5(20) + 3 = 103"

Submit
