Options: Graphing on graph paper, Substitution, Elimination y = 2x-2 y = -2x+6 ( , ) Charles has a collection of dimes and quarters worth$1.25. He has 8 coins. Which option best representsa system of equations for this situation? x + y = 1.25 0.10x + 0.25y = 8 x + 0.25y = 1.25 x + 0.10y = 8 0.10x + y = 8 x + 0.25y = 1.25 0.10x + 0.25y = 1.25 x + y = 8 A set of triangular and square tiles contains 50 piecesand 170 sides. Write a system of equations to representthis equation and solve for the number of triangular and square tiles. triangular tiles square tiles |
