Problema Solution
The number of right handed students in a mathematics class is nine times the number of left handed students. The total number of students in the class is 30. How many right handed students are in the class? How many left handed students are in the class?
Answer provided by our tutors
let
x = the number of right handed students
y = the number of left handed students
The number of right handed students in a mathematics class is nine times the number of left handed students:
x = 9y
The total number of students in the class is 30:
x + y = 30
by solving the system of equations:
x = 9y
x + y = 30
we find:
x = 27 right handed students
y = 3 left handed students
