Question

a biology class has a total of 38 students. the number of males is 8 more than the number of females. how many males and how many females are in the class? number of males: number of females:

Explanation:

Step1: Set up equations

Let the number of females be \(x\). Then the number of males is \(x + 8\). The total number of students is \(38\), so \(x+(x + 8)=38\).

Step2: Simplify the equation

Combine like - terms: \(2x+8 = 38\).
Subtract \(8\) from both sides: \(2x=38 - 8=30\).

Step3: Solve for \(x\)

Divide both sides by \(2\): \(x=\frac{30}{2}=15\).

Step4: Find the number of males

Since the number of males is \(x + 8\), substitute \(x = 15\) into it. The number of males is \(15+8 = 23\).

Answer:

Number of males: \(23\)
Number of females: \(15\)
