Exam 2: Linear Equations and Inequalities in One Variable

Answer the question or complete the sentence to make a true statement. -Under what condition will the sum of a positive number and a negative number be negative?

Use order of operations to simplify the expression. --18 - [( 7 - 4) - (-4 - 4)]

Give the numerical coefficient of the term. -Z

Provide an appropriate response. -The table shows the number of pupils per teacher in selected counties in a certain state. Which counties have a figure greater than 14.7?

Perform the indicated operation. -

Evaluate the expression for the given values. If necessary, round to the nearest tenth. - x = 6, y = 3

Simplify by finding the absolute value. --

Graph the numbers on a number line. -- 3 , -1, 1, 3

Simplify the expression. -5x + x

Find the sum. -15 7 + 6 + (-7) + (-6)

Rewrite the statement so the inequality symbol points in the opposite direction. -33 $\ge$ 1

Decide whether the problem is an equation or an expression. -4( 2x + 9) = 3( 8x - 4)

Simplify. - ÷ 9 - 7

Find the difference. -- -

Provide an appropriate response. -If a, b, and c are real numbers, is this statement true or false?

Find the solution of the equation from the given set. --x + 4 = -1; {-9, -5, -1, 0, 1, 5, 9}

Simplify the expression. -9g + 16 - 5

Write the expression without parentheses. --( 3x + 6y)

Rewrite the statement so the inequality symbol points in the opposite direction. -17 < 19

Choose the one alternative that best completes the statement or answers the question. Find the sum. --1.2 + [( -2.7) + ( -1.5)]
