Question 1

Which of the changes would keep the hanger in balance?

Select all that apply.

Question 2

Here is a balanced hanger diagram.

Each triangle weighs 2.5 pounds, each circle weighs 3 pounds, and x represents the weight of each square. Select all equations that represent the hanger.

Question 3

What is the weight of a square if a triangle weighs 4 grams?

Explain your reasoning.

Andre came up with the following puzzle. “I am three years younger than my brother, and I am 2 years older than my sister. My mom's age is one less than three times my brother's age. When you add all our ages, you get 87. What are our ages?”

Question 4

Try to solve the puzzle.

Question 5

Jada writes this equation for the sum of the ages: (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87

Explain the meaning of the variable and each term of the equation.

Question 6

Question 7

These two lines are parallel. Write an equation for each.

Question 1

Which of the changes would keep the hanger in balance?

Select all that apply.

Adding two circles on the left and a square on the right

Adding 2 triangles to each side

Adding two circles on the right and a square on the left

Adding a circle on the left and a square on the right

Adding a triangle on the left and a square on the right

Question 2

Here is a balanced hanger diagram.

Each triangle weighs 2.5 pounds, each circle weighs 3 pounds, and x represents the weight of each square. Select all equations that represent the hanger.

x + x + x + x + 11 = x + 11.5

2x = 0.5

4x + 5 + 6 = 2x + 2.5 + 6

2x + 2.5 = 3

4x + 2.5 + 2.5 + 3 + 3 = 2x + 2.5 + 3 + 3 + 3

Question 6

Write the equation with fewer terms.
