Answer:
The range of the numbers make this true is (12 , 17)
Step-by-step explanation:
Lets explain how to solve the problem
The statement is:
→ Nine less than a number is between 3 and 8
Assume that the number is x
∵ The number is x
∴ Nine less than a umber is x - 9
→ The difference is between 3 and 8
∴ 3 < x - 9 < 8
∴ Nine less than a number is between 3 and 8 ≡≡≡ 3 < x - 9 < 8
Lets solve the inequality to find the range of x
∵ 3 < x - 9 < 8
Add 9 to each side
∴ 3 + 9 < x - 9 + 9 < 8 + 9
∴ 12 < x < 17
∵ There is no mention about the type of the number that is integer or
rational number or real number
∴ The range of x is any number between 12 and 17
The range of the numbers make this true is (12 , 17)
Remember you can use any number between 12 and 17 but you
cannot use 12 or 17
The range of numbers that make this true is (12, 17).
Let the numbers be represented by x.
Therefore, based on the information given, the number will be:
x - 9 = 3
x = 3 + 9
x = 12
The first number is 12.
x - 9 = 8.
x = 8 + 9
x = 17
Therefore, the range of numbers that make this true is (12, 17).
