1. desmond wants to sell his car that he paid $8,000 for 2 years ago. the car depreciated, or decreased in value, at a constant rate each month over a 2-year period. if x represents the monthly depreciation amount, which expression shows how much desmond can sell his car for today? a.8,000 + 24x b.8,000 − 24x c.8,000 + 2x d.8,000 − 2x 2. avi and sergi are saving money to buy a game system. avi has $2 more than double the amount of money sergi has. together, they have $40. write an equation to determine how much money sergi and avi have together. a.x + 2x + 2 = 40 b.2x + 2 = 40 c.x + 2x − 2 = 40 d.2x − 2 = 40 isabella solved the following equation: 4x − 2x + 8 = 6(x + 4) step work justification 1 4x − 2x + 8 = 6x + 24 distributive property 2 2x + 8 = 6x + 24 combine like terms 3 −4x + 8 = 24 addition property of equality 4 −4x = 16 subtraction property of equality 5 x = −4 division property of equality which step has an incorrect justification? a.step 1 b.step 2 c.step 3 d.step 4

Caleb solved this equation and recorded his work. 7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6 1. 7.4x + 8.2x − 16.4 = −2.3x + 13.8 − 21.6 2. 15.6x − 16.4 = −2.3x + 35.4 3. 17.9x − 16.4 = 35.4 4. 17.9x = 51.8 5. x ≈ 2.89 when caleb verified his solution, it didn’t work. what mistake did he make? in step 1, the distributive property was not used properly on the right side of the equation. in step 2, the like terms were not combined properly on the right side of the equation. in step 3, the addition property of equality was not used properly to isolate the variable term. in step 5, the division property of equality was not used properly to solve for x.
