The number of students in a school's math club is ten less than twice the number of students in the art club. Let a represent the number of students in the art club. Write an expression for the number of students in the math club.

   2a - 10

Step-by-step explanation:

a represents the number of students in the art club.

The number of students in a school's math club is ten less than twice the number of students in the art club.

ten less = - 10

twice the number of students in the art club = 2*a

2a - 10 = the number of students in the math club

We will use the property :

sum of interior angles on same side of transversal =180

(8x-14) + (2x+54)=180

10x+40=180

10x=140

x=14
