grade 8 illustrative math unit 4 Mid-study guide

After applying the distributive property to the following equation, what would be the result: -8(-8x - 6) = -8x - 22 + 2x

• 64x + 48 = -8x - 22 + 2x

• -64x - 48 = -8x - 22 + 2x

• 8x - 6 = -8x - 22 + 2x

After combining like terms in the following equation, what would be the result: 64x + 48 = -8x - 22 + 2x

• 64x + 48 = -10x -22

• 112 = -28x

• 64x + 48 = -6x - 22

After moving the variable to one side in the following equation, what would be the result: 64x + 48 = -6x - 22

• 70x + 48 = -22

• 58x + 48 = -22

• 48 = 70x - 22

After moving the constant to one side in the following equation, what would be the result: 70x + 48 = -22

• 70x = 70

• 70x = -70

• 70x + 70 = 0

What is the solution to the equation: 70x = -70

• 1

• 70

• -1

• -70

What is c?
2c-12 = 9c + 2

• c = 14
• c = 2
• c= -2
