On a math test, 60%of students use a pencil, half of the remaining students used a red pen if 6 students use a red pen, how many students are in the class

30 people are in the class

Hi!

If 60% of the students used a pencil, then the remaining percentage of the class is 40%, as 60% + 40% = 100%. Since half of that remaining percentage, or half of 40%, used a red pen, then that means 20% used a red pen.

Since 6 students used a red pen, and that is 20%, that means 6 is 20% of the total students in the class.

To get 100%, just multiply both by 5, and you get 30 for 100% of the students.

Therefore, there are 30 students in the class.

Hope this helped!

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
