### Solved Example

**Question:**One number is 12 more than another number. The sum of the smaller number is more than two times the larger number which is 30. What are the two numbers?

**Solution:**

Let x be the smaller number.

Then, the larger number is 12 more = x + 12

The problem states,

x + 2(x + 12) = 30

=> x + 2x + 24 = 30

=> 3x + 24 = 30

Subtract 24 from both sides of the equation,

=> 3x + 24 - 24 = 30 - 24

=> 3x = 6

Divide both side by 3,

=> x = 2, is the smaller number.

So, the larger number is x + 12 = 2 + 12 = 14.

## College Algebra Homework Help

Back to TopLearn Algebra from solving equations to logarithms and sketching graphs to complex numbers. College Algebra covers a range of topics like linear equations, quadratic equations, matrices, logarithms and polynomials. Free online Algebra solvers are readily available and cover all the topics that are a part of the college syllabus. Students will gain an in-depth understanding of Algebraic principles and learn how to use them to solve problems. College Algebra equation solvers give step by step solutions to each problem and explain how each step leads to the next with the right operations or rules involved.

### Solved Example

**Question:**The base of a triangle is 7 m more than its altitude. If the area of the triangle is 15 square m. Find its altitude.

**Solution:**

Let the altitude of the triangle (AD) = x

therefore, base of the triangle (BC) = x + 7

Given, area of the triangle = 15

Step 1:

Step 1:

Area of the triangle = $\frac{1}{2}$ Base * Height

=> 15 = $\frac{1}{2}$ * (x + 7) * x

=> 15 * 2 = (x + 7) * x

=> 30 = x

^{2}+ 7x

x

^{2}+ 7x - 30 = 0

Step 2:

Step 2:

Solve for x, x

^{2}+ 7x - 30 = 0

=> x

^{2}+ 10x - 3x - 30 = 0

=> x(x + 10) - 3(x + 10) = 0

=> (x - 3)(x + 10) = 0

Step 3:

Step 3:

Either x - 3 = 0 or x + 10 = 0

=> x = 3 or x = - 10

Length must be positive. So, neglect x = - 10.

Hence, altitude of the triangle is 3 m.

Chapters are divided into sections that are organized around core topics. Within each section, lessons include activities, challenging problems, investigations and practice problems. Teacher notes for each lesson include a “suggested lesson activity” section with ideas for lesson introduction, specific tips and strategies for lesson implementation to clearly convey core ideas, and a means for bringing the lesson to closure. Read More...

Core ideas are synthesized in “Math Notes” boxes throughout the text. These notes are placed in a purposeful fashion, often falling one or more lessons after the initial introduction of a concept. This approach allows students time to explore and build conceptual understanding of an idea before they are presented with a formal definition or an algorithm or a summary of a mathematical concept. “Math Notes” boxes include specific vocabulary, definitions and instructions about notation, and occasionally interesting extensions or real-world applications of mathematical concepts.

Learning Log reflections appear periodically at the end of lessons to allow students to synthesize what they know and identify areas that need additional explanation. Toolkits are provided as working documents in which students write Learning Logs, interact with Math Notes and create other personal reference tools.

Each chapter offers review problems in the chapter closure: typical problems that students can expect on an assessment, answers, and support for where to get help with the problem. Chapter closure also includes lists of Math Notes and Learning Logs, key vocabulary in the chapter, and an opportunity to create structured graphic organizers.

The books include “Checkpoints” that indicate to students where fluency with a skill should occur. Checkpoints offer examples with detailed explanations, in addition to practice problems with answers.

In addition, CPM provides a *Parent Guide with Extra Practice* available for free download cpm.org of in booklet form for purchase. In addition to practice problems with answers, the *Parent Guide with Extra Practice* provides examples with detailed explanations and guidance for parents and tutors.

Each chapter comes with an assessment plan to guide teachers into choosing appropriate assessment problems. CPM provides a secure online test generator and sample tests. The Assessment Guidebook contains guidance for a wide variety of assessment strategies.

Technology is used in the course to allow students to see and explore concepts after they have developed some initial conceptual understanding. The course assumes that classes have access to at least one of these three technology setups: a set of graphing calculators and whole-class display technology for the teacher, a full computer lab with computers that have graphing software for each student, or a classroom computer with graphing software equipped with projection technology.
