Ten Less Than Twice a Number is Equal to At Least 52: Finding All Possible Values of the Number

Introduction

In this article, we will explore a mathematical problem that involves solving an inequality to find all possible values of a number. The problem states that ten less than twice a number is equal to at least 52. We will use the letter x as the variable and write the inequality so that it can be solved to find the possible values of x.

Writing the Inequality

To write the inequality, we need to translate the given problem into a mathematical expression. Let's break down the problem:

"Ten less than" means we need to subtract 10 from the expression.
"Twice a number" means we need to multiply the number by 2.
"is equal to at least 52" means we need to set up an inequality with 52 as the minimum value.

Using the variable x, we can write the inequality as:

2x - 10 ≥ 52

Solving the Inequality

To solve the inequality, we need to isolate the variable x. We can do this by adding 10 to both sides of the inequality:

2x ≥ 52 + 10 2x ≥ 62

Next, we can divide both sides of the inequality by 2 to solve for x:

x ≥ 62/2 x ≥ 31

Finding All Possible Values of x

Now that we have solved the inequality, we can find all possible values of x. Since x ≥ 31, we know that x can be any value greater than or equal to 31. This means that x can be 31, 32, 33, 34, and so on.

Conclusion

In this article, we have solved an inequality to find all possible values of a number. We started with a problem that stated ten less than twice a number is equal to at least 52 and wrote the inequality 2x - 10 ≥ 52. We then solved the inequality by adding 10 to both sides and dividing both sides by 2, resulting in x ≥ 31. Finally, we found all possible values of x, which are any values greater than or equal to 31.

Step-by-Step Solution

Here is a step-by-step solution to the problem:

Write the inequality: 2x - 10 ≥ 52
Add 10 to both sides: 2x ≥ 52 + 10
Simplify the right-hand side: 2x ≥ 62
Divide both sides by 2: x ≥ 62/2
Simplify the right-hand side: x ≥ 31

Graphical Representation

Here is a graphical representation of the solution:

The inequality x ≥ 31 represents a line on the number line that starts at 31 and extends to the right.
The values of x that satisfy the inequality are all the points on the number line that are greater than or equal to 31.

Real-World Applications

This problem has real-world applications in many areas, such as:

Finance: When investing in stocks or bonds, it's essential to consider the minimum return on investment, which can be represented by the inequality x ≥ 31.
Science: In scientific experiments, it's crucial to consider the minimum value of a variable, which can be represented by the inequality x ≥ 31.
Engineering: In engineering design, it's essential to consider the minimum value of a variable, which can be represented by the inequality x ≥ 31.

Common Mistakes
