A factored form of 6a is a a a a ( a) a 6a a 6. If a and b -, then ab 6 b 7. The sum of two numbers is. If one number is, then in terms of, the other number is

5 ELEMENTARY ALGEBRA This practice test measures our abilit to perform basic algebraic operations and to solve problems that involve elementar algebraic concepts. Directions: Solve each of the following problem in the space to the right of the question as provided and indicate ou answer b circling it Appl the distributive law of multiplication & watch our signs.. If, then If, 6 9 then Multipl: remember that eponents add when ou multipl this If a and b -, then ab 6 b 7. The sum of two numbers is. If one number is, then in terms of, the other number is ab 6 6 b To make it easier for ou, let the unknown number or other number be represented b.. A factored form of 6a is a a a a ( a) a 6a a Thinking of the Reverse FOIL method (factoring), ou ll need the Outside & Inside multiplicands to cancel out for this result: a a 6 6a a a a Therefore: Now solve for :

6 8. If , then Which of the following is a factor of 7 0? Multipl it times: Remember that eponents add when ou multipl this. Use the FOIL method: Use the reverse FOIL method (factoring): One of the solutions to the equation 08 0 is If +, then Use the reverse FOIL method (factoring): 0 Solve each factor for : Cross multipl &solve for :. Art downloaded apps per hour for t hours. In terms of t, what number of apps did he download? Rate apps per hour Rate apps hour # of hours time (t hour) t t t Multipl b number of hours to give number of apps. apps hour (t hour) t apps +t

7 The length of a rectangle is 7 inches greater than its width. Which of the following epressions represents its area in terms of its width, w? ww 7 w 7 w 7 ww 7 8. If 9 is divided b, the remainder is If 6, then Find the least common denominator: st : Multipl Area l w (l)ength w + 7 (w)idth w Area ww 7 9 Use the FOIL method: nd : Compare Remainder: Cross multipl: 0. Which of the following could represent the graph?. b 6 b b 8b 6b 6 0. In the solution of the sstem of equations above, what is the value of? - Tr some test coordinates X Y So the line must pass through the (0,0) coordinate which eliminates answers &. Since the values of X & Y are either both positive or both negative cannot be the correct answer. b b b 9 6b 9b 6b Solve for : Now substitute for in: Now solve for :

8 . If +, then ; Cross multipl & solve for : 6. b + b (b ) b + b b + b + b b b + b (b ) b + b b + b + b ( + ) ( ) b + b Find the least common denominator:. If a b c e, then b e ac b+e a+c a b c e -c -c a c b e +b +b a c b e b e a c (a c) b e b e a c b e ac. a a a a a a a a a a a( a) a a STOP!
