Answer:
5. To isolate x, the variable representing the total number of students, we can divide both sides of the equation by 2:
x = 56 / 2
x = 28
Therefore, the total number of students in the art class is 28.
Explanation:
To find the total number of students in the art class, we need to use the given ratio and information about the number of students wearing glasses.
1. The ratio of the total number of humans in the art class is given as 2 to 7. This means that for every 2 humans, there are 7 students.
2. We are also given that there are 8 students wearing glasses.
3. To find the total number of students in the class, we can set up a proportion using the ratio and the information about the number of students wearing glasses.
Let's set up the proportion:
2/7 = 8/x
Here, x represents the total number of students in the class.
4. To solve the proportion, we can cross-multiply:
2 * x = 7 * 8
Simplifying the equation, we have:
2x = 56
