Answer:
5 ≤ x ≤ 50; Billy needs to make at least 5 more pizzas but no more than 50
Step-by-step explanation:
Let
x -----> the number of pizzas
we have the compound inequality
Divide the compound inequality into two inequalities
----> inequality A
The solution of the inequality A is the interval -----> (-∞,50]
-----> inequality B
Rewrite
The solution of the inequality B is the interval -----> [5,∞)
therefore
The solution of the compound inequality is
(-∞,50] ∩ [5,∞)=[5,50]
so
Billy needs to make at least 5 more pizzas but no more than 50
