For each sentence below, use the drop-down menu to select a symbol that correctly indicates the relationship.
three is less than a number. 3 < x
one more than a number is at least seven. x + 1 > 7
the maximum value of a number is 29. x < 29
the difference of a number and ten is at least 91. x - 10 > 91

Step-by-step explanation:

Let the unknown number be x

Three is less than a number: for less than we use < symbol

3 < a number becomes

One more than a number is at least seven: Number atleast 7 means 7 or more than 7. So we use ≥ 7. One more than a number is x+1

The maximum value of a number is 29: maximum value of x is 29 , so 29 or less than 29. Use ≤ symbol

The difference of a number and ten is at least 91: The difference of a number and 10 is x-10. For at least we use ≥ because 91 is included.
