Solving a word problem using a system of linear inequalities
1 answer:
Inequalities help us to compare two unequal expressions. The shaded potion can be made as shown below.
<h3>What are inequalities?</h3>Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
Rita does a weekly exercise program consisting of cardiovascular work and weight training. Each week, she exercises for at least 11 hours. She spends at most 7 hours on weight training. She spends at most 8 hours doing cardiovascular work.
Therefore, For the given condition let x denote the time (in hours) that Rita spends doing cardiovascular work. Let y denote the time (in hours) that she spends on weight training.
Now, the inequalities can be written as,
x + y > 11
x ≤ 7
y ≤ 8
Hence, the shaded potion can be made as shown below.

<h3>How to illustrate the triangle?</h3>Based on the information, the reflexive property of equality states that an angle or shape is always congruent to itself.
The alternate interior angle theorem is that when two parallel lines are cut by a transversal, then the alternate interior angles are the same.
