Question 1 (Multiple Choice Worth 4 points) (2.01) Solve: 4(x + 1) = 4x + 4 No Solution 0 All Real Numbers 1 Question 2 (Multiple Choice Worth 4 points) (2.02) The length of a rectangle is 24 units. Can the perimeter x of the rectangle be 60 units when its width y is 11 units? No, the rectangle cannot have x = 60 and y = 11 because x = 48 + 2y. No, the rectangle cannot have x = 60 and y = 11 because x = 24 + 2y. Yes, the rectangle can have x = 60 and y = 11 because x + y is greater than 48. Yes, the rectangle can have x = 60 and y = 11 because x + y is greater than 24. Question 3 (Multiple Choice Worth 5 points) (2.06) Zoya has to earn at least $300 to meet her fundraising goal. She has only 100 bracelets that she plans to sell at $5 each. Which inequality shows the number of bracelets, x, Zoya can sell to meet her goal? 60 ≤ x ≤ 100 60 ≤ x ≤ 300 100 ≤ x ≤ 300 20 ≤ x ≤ 100 Question 4 (Multiple Choice Worth 4 points) (2.01) Solve: 4(2x - 1) - 3 = 9(x - 4) -29 32 13 29 Question 5 (Multiple Choice Worth 4 points) (2.05) Which of the following is not a way to represent the solution of the inequality 2(x - 1) less than or greater to 10? x 6 6 x A number line with a closed circle on 6 and shading to the left A number line with a closed circle on 6 and shading to the right Question 6 (Multiple Choice Worth 5 points) (2.07) The equation below shows the area of a trapezoid, A, with a height of 9 cm, and one base 35 cm. A = 9 over 2(b + 35) Which of the following formulas correctly solves for the other base, b? b = 2A over 9 + 35 b = 2 multiplied by A over 9 - 35 b = 2 multiplied by A plus 35, all over 9 b = 2 multiplied by A minus 35, all over 9 Question 7 (Multiple Choice Worth 5 points) (2.06) A company did a quality check on all the packs of nuts it manufactured. Each pack of nuts is targeted to weigh 18.25 oz. A pack must weigh within 0.36 oz of the target weight to be accepted. What is the range of rejected masses, x, for the manufactured nuts? x < 17.89 or x > 18.61 because |x - 18.25| > 0.36 x < 17.89 or x > 18.61 because |x - 0.36| + 18.25 > 0 x < 18.25 or x > 18.61 because |x - 18.25| > 0.36 x < 18.25 or x > 18.61 because |x - 0.36| + 18.25 > 0 Question 8 (Multiple Choice Worth 5 points) [2.07] Solve for pi: C = 2pir. pi equals 2 times C over r pi equals C over quantity 2 times r pi pi equals C over r pi equals r times C over 2 Question 9 (Multiple Choice Worth 5 points) (2.05) Choose the missing step in the given solution to the inequality -2x - 14 > -4 + 3x. -2x - 14 > -4 + 3x -5x - 14 > -4 x < -2 -5x < 10 -5x > -28 x < 2 -5x > 10 Question 10 (Multiple Choice Worth 4 points) (2.03) Below are the steps to solve an equation: Step 1: |x - 4| + 1 = 8 Step 2: |x - 4| = 8 - 1 Step 3: |x - 4| = 7 Which of the following is a correct next step to solve the equation? x - 4 = -7 x + 4 = -7 -x - 4 = 7 x + 4 = 7 Question 11 (Multiple Choice Worth 5 points) (2.05) Abbey wants to use her savings of $1325 to learn yoga.
