Question

there are 48 students in the kennedy middle school student council. the number of 8th graders is 12 fewer than three times the number of 7th graders

Answer 1

Answer: 36 8th graders and 12 7th graders

Explanation:

48-12=36

36 divided by 3=12

With this information, 12 7th graders and 36 8th graders

Answer 2

3 * 15 - 12 = 33 So, the equation is saying that the result of 3 times 15 minus 12 is equal to 33.

Explanation:

Let's call the number of 7th graders "x". Then, the number of 8th graders is 3 * x - 12.

The total number of students in the student council is 48, so we can set up an equation:

x + (3 * x - 12) = 48

Expanding and simplifying:

4x - 12 = 48

Adding 12 to both sides:

4x = 60

Dividing both sides by 4:

x = 15

So, there are 15 7th graders and 3 * 15 - 12 = 33 8th graders in the Kennedy Middle School student council.
