Three-fifths Of The Members Of The Spanish Club Are Girls. There Are A Total Of 30 Girls In The Spanish Club. Which Statements Can Be Used To Solve For $x$, The Total Number Of Members In The Spanish Club? Select Three Options.A.
Introduction
In this problem, we are given that three-fifths of the members of the Spanish club are girls, and there are a total of 30 girls in the club. We need to find the total number of members in the club, denoted by $x$. In this article, we will explore three different statements that can be used to solve for $x$.
Statement 1: Three-fifths of the members are girls
Let's start by analyzing the first statement: "Three-fifths of the members are girls." This statement can be represented mathematically as:
where $x$ is the total number of members in the club. To solve for $x$, we can multiply both sides of the equation by $\frac{5}{3}$:
Therefore, the total number of members in the club is 50.
Statement 2: The number of girls is three-fifths of the total number of members
The second statement is similar to the first one, but it is phrased differently: "The number of girls is three-fifths of the total number of members." This statement can be represented mathematically as:
To solve for $x$, we can multiply both sides of the equation by $\frac{5}{3}$:
Therefore, the total number of members in the club is 50.
Statement 3: The number of girls is 30, and the number of boys is two-fifths of the total number of members
The third statement is a bit more complex: "The number of girls is 30, and the number of boys is two-fifths of the total number of members." This statement can be represented mathematically as:
To solve for $x$, we can first multiply both sides of the equation by 5:
Next, we can subtract $5x$ from both sides of the equation:
Finally, we can divide both sides of the equation by -3:
Therefore, the total number of members in the club is 50.
Conclusion
Introduction
In our previous article, we explored three different statements that can be used to solve for the total number of members in the Spanish club. In this article, we will answer some frequently asked questions (FAQs) related to the problem.
Q: What is the total number of members in the Spanish club?
A: The total number of members in the Spanish club is 50.
Q: How do I know that three-fifths of the members are girls?
A: The problem states that three-fifths of the members are girls, which means that the number of girls is 3/5 of the total number of members.
Q: Can I use a different fraction to represent the number of girls?
A: Yes, you can use a different fraction to represent the number of girls. For example, you can use 3/4 or 2/3, but you will need to adjust the equation accordingly.
Q: How do I solve for x if I know that the number of boys is two-fifths of the total number of members?
A: If you know that the number of boys is two-fifths of the total number of members, you can set up an equation using the following formula:
To solve for x, you can follow the steps outlined in our previous article.
Q: Can I use algebraic manipulation to solve for x?
A: Yes, you can use algebraic manipulation to solve for x. For example, you can multiply both sides of the equation by 5 to eliminate the fraction:
Next, you can subtract 5x from both sides of the equation to get:
Finally, you can divide both sides of the equation by -3 to get:
Q: What if I want to find the number of boys in the Spanish club?
A: If you want to find the number of boys in the Spanish club, you can use the following formula:
Since we know that x = 50, we can plug in this value to get:
Therefore, the number of boys in the Spanish club is 20.
