Problema Solution
The teacher separated her class of thirty-three students into two groups. One group has 9 more than twice as many students as the other group. Use variable s for the group with less students. Write an equation in terms of the group with less students
Answer provided by our tutors
s = the number of students in the group with less students
33 - s = the number of students in the other group
One group has 9 more than twice as many students as the other group - meaning the group with more students has 9 more than twice as many students as s:
33 - s = 9 + 2s is the equation in terms of the group with less students
by solving for s for as we find
s = 8 students
