Which of the following is not a way to represent the solution of the inequality 2(x − 1) less than or equal to 10? x less than or equal to 6 6 greater than or equal to 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 12(Multiple Choice Worth 1 points) (02.02) The width of a rectangle is 12 units. Can the perimeter x of the rectangle can be 60 units when its length y is 18 units? No, the rectangle cannot have x = 60 and y = 18 because x + y is less than 60 No, the rectangle cannot have x = 60 and y = 18 because x + y is less than 24 Yes, the rectangle can have x = 60 and y = 18 because x = 12 + 2y Yes, the rectangle can have x = 60 and y = 18 because x = 24 + 2y Question 13(Multiple Choice Worth 1 points) (02.06) A company did a quality check on all the packs of trail mix it manufactured. Each pack of trail mix is targeted to weigh 9.25 oz. A pack must weigh within 0.23 oz of the target weight to be accepted. What is the range of rejected masses, x, for the manufactured trail mixes? x < 9.02 or x > 9.48 because |x − 0.23| + 9.25 > 0 x < 9.25 or x > 9.48 because |x − 9.25| > 0.23 x < 9.25 or x > 9.48 because |x − 0.23| + 9.25 > 0 x < 9.02 or x > 9.48 because |x − 9.25| > 0.23 Question 14(Multiple Choice Worth 1 points) (02.07)Solve for H: A = L ⋅ W ⋅ H H = A times W over L H = W times L over A H = L times A over W H = A over quantity L times W Question 15(Multiple Choice Worth 1 points) (02.01) Solve −4(x + 10) − 6 = −3(x − 2). −40 −46 −52 52 Question 16 (Fill-In-The-Blank Worth 1 points) (02.01) Kyra observed that 85% of the students at a library liked reading mystery stories.
