DirectionsFor questions 16 through 20, solve the problem and enter your answer in the grid, as described below, on the answer sheet.

1.Although not required, it is suggested that you write your answer in the boxes at the top of the columns to help you fill in the circles accurately. You will receive credit only if the circles are filled in correctly.2.Mark no more than one circle in any column.3.No question has a negative answer.4.Some problems may have more than one correct answer. In such cases, grid only one answer.5.Mixed numbers such as three and one half must be gridded as 3.5 or sevenslashtwo. (If three,one,slash,two, is entered into the grid, it will be interpreted as thirty one halves, not three and one half.)6.Decimal answers: If you obtain a decimal answer with more digits than the grid can accommodate, it may be either rounded or truncated, but it must fill the entire grid.

The following are four examples of how to record your answer in the spaces provided. Keep in mind that there are four spaces provided to record each answer.Examples 1 and 2

Begin skippable figure description.Example 1: If your answer is a fraction such as seventwelfths, it should be recorded as follows. Enter 7 in the first space, the fractionbar (aslash) in the second space, 1 in the third space, and 2 in the fourth space. All four spaces would be used in this example.

Example 2: If your answer is a decimal value such as 2.5, it could be recorded as follows. Enter 2 in the secondspace, the decimal point in the third space, and 5 in the fourth space. Only three spaces would be used in thisexample.End skippable figure description.

Example 3

Begin skippable figure description.Example 3: Acceptable ways to record twothirds are: 2 slash 3, .666, and .667.End skippable figure description.

Example 4

Note: You may start your answers in any column, spacepermitting. Columns you dont need to use should be left blank.Begin skippable figure description.Example 4: It is not necessary to begin recording answers in the first space unless all four spaces are needed. For example, if your answer is 201, you may record 2 in the second space, 0 in the third space, and 1 in the fourth space. Alternatively, you may record 2 in the first space, 0 in the second space, and 1 in the third space. Spaces not needed should be left blank.End skippable figure description.

Answers and Explanations for Questions1 through20

Explanation for question 1.Choice C is correct. Subtracting 6 from each side of 5x plus 6 equals10 yields 5x equals4. Dividing both sides of 5x equals4 by 5 yields x equals fourfifths. The value of x can now be substituted into the expression 10x plus 3, giving 10, parenthesis, fourfifths, close parenthesis, plus 3, equals11.

Alternatively, the expression 10x plus 3 can be rewritten as 2,parenthesis, 5x plus 6, close parenthesis, minus9, and 10 can be...
