A circle has a mass of 3 grams and a square has a mass of 2 grams. Which is the mass of a triangle?

5

Solve this equation:

5

What type of solution does this equation have?

3x + 8 = 3x + 2 - 10

5

Does this equation have a solution that is positive, negative, or zero?

3x + 2 = -5

5

Order these steps to solving this equation:

x - 4(x - 1) = x + 2x + 3

6 = 6x
6x - 9(x-1) = x + 2x + 3 (original equation)
6x - 9x + 9 = x + 2x + 3
9 = 6x + 3
x = 16
-3x + 9 = 3x + 3

5

Did Ms. Allen solve this equation correctly?

8(x - 3) + 7 = 2x(4 -17)
8(x - 3) + 7 = 2x(13)
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-0.5 = x

5

Match the equation balancing steps with the description of what was done in each step.

12x - 6 = 10
6x - 3 = 5
6x - 3 = 5
6x = 8
6x = 8
x = 8/6
4x + 2 = 12
2x + 1 = 6

Add 3 to both sides
Divide both sides by 2
Multiply both sides by 1/6

5

Which of the following would keep the hanger balanced?

5

Which equation could describe this hanger?

Clare asks Andre to play the following number puzzle:
Pick a number
Add 2
Multiply by 3
Subtract 7
Add your original number
Andre’s final result is 27. What number did he start with?

5

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.

5

Ms. Allen solved the equation but she knows she solved it incorrectly.
FIRST - Circle her mistake.
THEN - Solve the equation correctly.

5

Solve for n.

3(n+2)=9(6−n)

Just write the number.

5

Solve for x.

2x+7−5x+8=3(5+6x)−12x
Just write the number.

5

What type of solution does this equation have?

x−3=2x−3−x

5

Write the other side of this equation so that it's true for all values of x.

5

Solve for x.

3(x+5)=6

Just write the number.

5

Decide whether this equation is true for all, one, or no values of x.

9(x−2)=7x+5

5

Here is an equation:

What could you write after the "+" so that the equation would be true for all values of x? (Infinitely many solutions)

5

In a basketball game, Elena scores twice as many points as Tyler. Tyler scores four points fewer than Noah, and Noah scores three times as many points as Mai. If Mai scores 5 points, how many points did Elena score?

Just write the number.
