Answer:
[tex]3 < x[/tex]
[tex]x + 1 \geq 7[/tex]
[tex]x \leq 29[/tex]
[tex]x - 10 \geq 91[/tex]
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 [tex]3 < x[/tex]
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
[tex]x + 1 \geq 7[/tex]
The maximum value of a number is 29: maximum value of x is 29 , so 29 or less than 29. Use ≤ symbol
[tex]x \leq 29[/tex]
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.
[tex]x - 10 \geq 91[/tex]
