Multiple Choice

Which equation represents the hanger using $$x$$ for the triangles and $$y$$ for the squares?

• x + y = 12
• 6x + 4y = 0
• 5x - 2y = 4
• 2x + 3y = 10

• Madrid
• Rome
• Paris

Multiple Choice

What is the result of Andre’s first step when solving $$2x+6=3x-8$$ ?

• 2x + 6 = 3x - 8 + 2x
• 2x + 6 - 3x = -8
• 2x + 6 = 3x + 8
• 2x + 6 - 2x = 3x - 8 - 2x

Multiple Choice

What is the result of Diego’s first step in solving $$2x+6=3x-8$$ ?

• Subtract 2x from both sides to get 6 = x - 8.
• Divide both sides by 2 to get x + 3 = 1.5x - 4.
• Multiply both sides by 2 to get 4x + 12 = 6x.
• Add 6 to both sides to get 2x + 12 = 3x.
