Voting An appropriations bill passes the U.S. House of Representatives with 49 more members voting in favor than against. If all 435 members of the House vote for or against the bill, how many voted in favor and how many voted against?

Short Answer

Expert verified
In the U.S. House of Representatives, 242 members voted in favor of the appropriations bill, and 193 members voted against it.

Step by step solution

01

Assign Variables

Let x represent the number of members who voted in favor of the bill. Let y represent the number of members who voted against the bill.
02

Set up Equations

We are given that there were 49 more votes in favor than against. This can be represented as: \(x = y + 49\) We are also given that the total members in the House are 435 and all of them voted: \(x + y = 435\)
03

Solve the System of Equations

Now we have a system of two linear equations with two variables. We can solve this system by substituting the expression for x from the first equation into the second equation: \((y + 49) + y = 435\)
04

Simplify the Equation

Now, simplify the equation and solve for y: \(2y + 49 = 435\) Subtract 49 from both sides: \(2y = 386\) Now, divide both sides by 2: \(y = 193\)
05

Find the Value for x

Now that we have the value for y, we can plug it back into the first equation to find the value for x: \(x = 193 + 49\) \(x = 242\)
06

Interpret the Results

Thus, 242 members of the U.S. House of Representatives voted in favor of the appropriations bill, and 193 members voted against.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Algebraic Problem-Solving
Algebraic problem-solving is a critical skill in mathematics, particularly when dealing with systems of linear equations like the one presented in our voting problem. In this scenario, we employ algebra to explore the relationship between the number of votes in favor and against a bill. By assigning variables to unknown quantities (\(x\) for votes in favor, and \(y\) for votes against), we create algebraic expressions to mirror the real-world situation.

In the provided example, the process begins by setting up a pair of linear equations based on the information given. The first equation, \(___x__ = ___y__ + 49\), represents the majority in favor, while the second equation, \(x + y = 435\), reflects the total number of voting members. The key to algebraic problem-solving lies in manipulating these equations to isolate and calculate the unknowns. Simplification and substitution are used to solve the system efficiently, indicating the power and versatility of algebra in everyday problem scenarios.
Voting in Mathematics
Voting problems in mathematics often involve understanding and applying systems of linear equations. They abstract the complex real-world voting processes into numerical terms that can be analyzed algebraically. The appropriations bill exercise illustrates a common format where a balance or difference is considered, such as '49 more members voting in favor than against.'

In this context, mathematical tools enable us to predict outcomes or deduce missing information. Since each member can only vote 'for' or 'against,' we can construct a complete picture from partial data. In our example, solving the system of equations derives precise numbers of votes on each side. This mathematical modeling of voting scenarios extends beyond the classroom into various fields, including political science and economics, showcasing the relevance and application of math in interpreting democratic processes.
Finite Mathematics
Finite mathematics encompasses various topics that deal with mathematics in a finite or discrete setting, rather than continuous. It includes subjects like algebra, probability, statistics, and the mathematics of finance and voting systems. The voting scenario we solve is a practical example of how finite mathematics is applied. The appropriation bill's voting outcome is a finite set of options: in favor or against.

In this finite mathematical context, each member's vote is discrete, and the system of linear equations is used to calculate definitive outcomes from a limited number of possibilities. Concepts from finite mathematics are particularly useful in modeling scenarios where the variables are countable and distinct. By understanding the principles behind finite mathematics, students gain tools that have broad applications in decision-making processes, social sciences, and computer science, preparing them for real-world situations where the complexity of discrete variables must be managed systematically.

In the 7 th Congress (1937-1939) the U.S. House of Representatives had 333 Democrats, 89 Republicans, and 13 members of other parties. Suppose that a bill passed the House with 31 more votes in favor than against, with 10 times as many Democrats voting for the bill as Republicans, and with 36 more non- Democrats voting against the bill than for it. If every member voted either for the bill or against it, how many Democrats, how many Republicans, and how many members of other parties voted in favor of the bill?

Use Gauss-Jordan row reduction to solve the given systems of equation. We suggest doing some by hand, and others using technology. HINT [See Examples 1-6.] $$ \begin{aligned} \sqrt{x}+y+z+u+v &=15 \\ y-z+u-v &=-2 \\ z+u+v &=12 \\ u-v &=-1 \\ v &=5 \end{aligned} $$
