Answer:
The middle slab has 6 cubic feet of cement.
Step-by-step explanation:
In this case we have to make a subtraction to know the quantity of cement used in the middle slab. Mr. Alvarez uses 14 cubic feet total, and the extreme slabs have 4 cubic feet each one, this is:
Now subtraction the total cement and the used in the extreme slabs, we have:
The middle slab has 6 cubic feet of cement.

Step-by-step explanation:
The system of linear inequalities x + 10y ≤ 80, x ≥ 30 and y ≤ 4 is represented in a graph below
<h3>Graph of Linear Inequality</h3>The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.
To solve this problem, we would require the use of graph which can easily be done with a graphing calculator.
x + 10y ≤ 80
x ≥ 30
y ≤ 4
The graph of the inequalities is attached below
