To find 50% or half, of 31, you can just add 31 + 31.

Or, 31 x 2.

Or even the longer way, we know 3 + 3 = 6. So we can just add 0's: 30 + 30 = 60. That leaves us with the 1's. 1 + 1 = 2.

Take our 60 from earlier, and add 2. 60 + 2 = 62.

Check your answer. 62/2 = 31.

Your answer is 62

50% is another way to say 1/2.

The easiest way to answer this question is to multiply 31 by 2 because it 31 is half of a number, then the other half is the same as 31... so 31 x 2 = 62

So 50% of 62 is 31

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
