- 9 - 9 = 0
- 9 / 3 = 3
- 9 x 2 = 18.
Which of the following equations are true for the number 9?
Select all that apply A. 4÷□=9/4B.1/9=□÷9 C.7÷□=7/9 D. □÷1/9=8/1
None of the given equations are true for the number 9.
To determine which of the following equations are true for the number 9, we need to examine each equation and check if it is valid for the number 9. Let's consider each equation one by one:
1. 9 + 3 = 12: To check if this equation is true for the number 9, we need to perform the addition operation. 9 + 3 equals 12. Therefore, this equation is true for the number 9.
2. 9 - 5 = 4: Similarly, we can check if this equation is true for the number 9 by performing the subtraction operation. 9 - 5 equals 4. Therefore, this equation is true for the number 9.
3. 9 * 2 = 18: Again, we perform the multiplication operation to check if this equation is valid. 9 multiplied by 2 equals 18. Therefore, this equation is not true for the number 9.
4. 9 / 3 = 6: Lastly, we perform the division operation to check if this equation is valid. 9 divided by 3 equals 3, not 6. Therefore, this equation is also not true for the number 9.
Based on our calculations, equations 1 and 2 are true while equations 3 and 4 are not true for the number 9.
