Question

one solution to x<81 is 80. which of the following numbers is also a solution for this inequality? -1000000,81.01,1000000,800

Answer 1

We need x < 81 (numbers strictly less than 81). Check each:

- -1,000,000 < 81 — true
- 81.01 < 81 — false
- 1,000,000 < 81 — false
- 800 < 81 — false

So only -1000000 is also a solution.
