Question

Write the word sentence as an inequality:

39. A number ( t ) is less than 7.
40. A number ( m ) is at least -3.

Answer 1

The inequality for "A number (t) is less than 7" is written as t < 7. "A number (m) is at least -3" translates to the inequality m ≥ -3. Inequalities use symbols like '<', '>', and '≥' to indicate relationships between values.

Step-by-step explanation:

When writing the word sentence as an inequality:

1. A number ( t ) is less than 7. This can be written as the inequality t < 7. Here the '<' symbol represents that the variable t is less than the number 7.
2. A number ( m ) is at least -3. This is represented by the inequality m ≥ -3. The symbol '≥' means that m is greater than or equal to -3; it encompasses the idea that m can be exactly -3 or any number greater than -3.

When working with inequalities, it's essential to use the correct symbols to indicate the relationship between values, as the inequality symbol clearly conveys the nature of that relationship. Just like in sentences where words carry the meaning, in mathematics, the structure and the chosen symbols like '<', '>', and '≥' convey the meaning.
