Question

i need help and thanks

A child's sorting game has 31 shapes. Each piece is either a triangle or a square. The shapes have a total of 111 sides. Build a system of equations that can be used to find how many of each shape is used in the game.

Answer 1

let t=number of triangles
let s=squares
SO,
\[t+s=31\]
3t is the total number of sides all triangles
4s is the total number of sides all squares
SO,
\[3t+4s=111\]

Answer 2

yes thanks
