Question

Janelle is in charge of bringing in dry erase markers for everyone in her math group to use to work on a project. She brings 3 markers for each person in her group and 5 extra markers for everyone to share. If Janelle brings in 23 markers in all, which equation represents the information? Let x represent the number of students in Janelle’s group.

Answer 1

The equation that represents the information is 3x + 5 = 23, where x represents the number of students in Janelle’s math group. To solve for x, subtract 5 from both sides of the equation, then divide both sides of the equation by 3.

Step-by-step explanation:

The equation that represents the information is 3x + 5 = 23, where x represents the number of students in Janelle’s math group.

To solve this equation, we need to isolate x by performing opposite operations. First, we subtract 5 from both sides of the equation:

3x + 5 - 5 = 23 - 5

This simplifies to:

3x = 18

Next, we divide both sides of the equation by 3 to solve for x:

3x/3 = 18/3

This simplifies to:

x = 6

Therefore, there are 6 students in Janelle’s math group.

Answer 2

3x + 5 = 23 is the answer for the choice picker.
