Answer:
900 ≤ x ≤ 1000
Step-by-step explanation:
Given
Minimum = 900
Maximum = 1000
Required
Write and solve a compound inequality
Represent the number of seashells with x.
To solve this, we first consider the minimum.
The relationship between x and the minimum is:
x ≥ minimum
This gives
x ≥ 900
Then, we consider the maximum.
This is represented as:
x ≤ maximum
x ≤ 1000
The two inequalities are:
x ≥ 900 and x ≤ 1000
This can be rewritten as:
900 ≤ x and x ≤ 1000
Combine both:
900 ≤ x ≤ 1000
