Question

"Which equations below are true? Select all that apply. a. 45 = -9 = 45 x -9/ b. 45 = -9 = 45 x 9 C. 45 = -9 = 5 d. 45 : -9= -5 e. None of the above f. All of the above

Answer 1

The correct answer is 'd. 45 : -9 = -5', which is the only true equation among the provided choices.

Step-by-step explanation:

The question is asking which of the given equations are true.

Let's evaluate each of them:

1. a. 45 = -9 = 45 x -9: This equation is not true because 45 obviously does not equal to -9.
2. b. 45 = -9 = 45 x 9: This equation is also not correct because again, 45 does not equal -9.
3. c. 45 = -9 = 5: This equation is also false for the same reason as above.
4. d. 45 : -9= -5: This equation is true. Division of two numbers with opposite signs results in a negative number. Therefore, when 45 is divided by -9, it equals -5.
5. e. None of the above: This option is not correct because there is one correct equation.
6. f. All of the above: This choice is also not correct because not all of the equations are true.
