What inequality shows that −2 is less than a number 5 units to its right?
A. −2 < 7
B. −2 < 3
C. −2 < 5
D. −2 < −7
B. -2 < 3
To show that -2 is less than a number 5 units to its right, we need to add 5 to -2 and compare it to the original number. Let's solve it step-by-step.
1. Start with the original number: -2
2. Add 5 units to the right: -2 + 5 = 3
So, the resulting number is 3.
Now, we need to compare -2 with the resulting number. Since -2 is less than 3, the correct inequality is:
B. -2 < 3
