PRAXIS Elementary Education: Multiple Subjects Mathmatics (5003) Practice Test Questions (form 3) County Population Brookhaven 74,702 Columbus 70,472 Davidson 74,072 Washington 74,720 The chart shows the populations of four neighboring counties. Quyen lives in the county with a population of 70,000+4,000+70+270,000+4,000+70+2. In which county does Quyen live? A.Brookhaven B.Columbus C.Davidson D.Washington C. Davidson The question requires an understanding of how to compose and decompose multidigit numbers. The expanded form 70,000+4,000+70+270,000+4,000+70+2 corresponds to the number 74,072, which is the population of Davidson County. Which of the following is an algebraic expression? A.6x−4 B.6y4 C.6z=4 D.6+4 A. 6x-4 The question requires an understanding of how to differentiate between algebraic expressions and equations. An algebraic expression is made of constants, variables, and algebraic operations. While (A) is an algebraic expression, (B) is an algebraic inequality, (C) is an algebraic equation, and (D) is a numerical expression. (2/3)/(4/3)+(3/5)x(5/3)^2 Which of the following is equivalent to the expression shown? A. 2/9 B. 13/6 C. 23/9 D. 55/18 B. 13/6 The question requires an understanding of how to solve problems using the order of operations. By using the order of operations and the fact that dividing is equivalent to multiplying by the inverse, the expression (2/3)/(4/3)+(3/5)x(5/3)^2 can be simplified to (2/3)x(3/4)+(3/5)x(25/9). Performing both multiplications yields (1/2)+(5/3), which is equivalent to (13/6). Mary has a rectangular garden in her backyard. The garden measures 5(3/4) feet wide by 7(1/2) feet long. What is the area of the garden?
