For each sentence below, use the drop-down menu to select a symbol that correctly indicates the relationship.

Answer 1

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

Answer 2

Answer:

$3 < x$

  $x + 1 \geq 7$

 $x \leq 29$

$x - 10 \geq 91$

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 $3 < x$

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

           $x + 1 \geq 7$

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

            $x \leq 29$

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.

           $x - 10 \geq 91$
