  1. Midterm Study Guide 2) Simplify: 1) Simplify:

  2. 4) Simplify: Midterm Study Guide 3) Simplify: Distribute the 8 to both terms in side the ( ) First combine all terms that are the same.

  3. Midterm Study Guide 5) Which algebraic expression goes with the phrase: 6 less than a number n – 6 Reminder: the phrase less than means you have to switch the first & second terms places

  4. Midterm Study Guide 6) A candy store sells packages of candy bars. Mark bought c candy bars for $30. What algebraic expression would show the cost of one candy bar? or

  5. x + 1 x + 3 x + 3 2x + 1 Midterm Study Guide 7) Write an expression for the perimeter of the given figure. Then simplify the expression. Remember: Perimeter means to add up all the sides. x + 1 x + 3 x + 3 2x + 1 + 5x + 8

  6. Midterm Study Guide 9) Solve: + 9 +9 + 4 +4 8) Solve: 12 16 5· ·5 - 4 -4 m = 60 y = -4

  7. Midterm Study Guide 10) Solve: 1st combine like terms + 8 +8 Then solve it like another 2-step equation. 6 6

  8. Midterm Study Guide 1st multiply both sides by the denominator 11) Solve: Then solve like another 2-step equation -2 -2

  9. Midterm Study Guide 12) Billie Joe Bob has received scores of 80, 75, 83, 92, and 75 on math quizzes. What score must Billie Joe Bob get on her next quiz to have an average of 80? 1st add up all of his current quiz scores 3rd find the difference between the two # 2nd multiply the average by 6 (6 representing the total # of quizzes taken) Billie needs a 75% on his next quiz.

  10. Midterm Study Guide 13) Identify what it mean to find the absolute value. The distance a number is from zero.

  11. Midterm Study Guide 1 14) Simplify: (3n – 2d + 5) – (6n +4d – 4) 1st distribute the negative 1 to all three terms 2nd match up the like terms from the first group of ( ) then combine them. The final answer is

  12. Midterm Study Guide 15) Simplify: -4(x – 3) + 5(–8 – x) Given that x = 3, evaluate the expression. -4(3– 3) + 5(–8 – 3) 1st substitute the 3 in for each x. Then use order of operations to solve the expression. -4(0) + 5(-11) 0+ -55 =-55

  13. x -1 x x+2 Midterm Study Guide 16) The perimeter of the triangle is 19 yards. Simplify the algebraic expressions to find the lengths of the sides of the triangle. 1st add up all the sides values. Then add on =19 & solve for the x value. 3 3 = 6 = 5 x x – 1 x + 2 3x + 1= 19 - 1 -1 = 8 3x = 18 After finding the value for x plug 6 in to find the side’s value. 3x + 1 x = 6

  14. Midterm Study Guide 17) A scuba diver is 25 feet below sea level while a seaplane is 85 feet above sea level. How far apart above the scuba diver is the seaplane? Hint: Think of using a tape measure to find the distance of the diver and the seaplane. 110 25 + 85 =

  15. Midterm Study Guide 18)Chris bought a hat for $10 and five pairs of socks. The total cost was $22.75. If each pair of socks cost the same amount, how much was one pair of socks? - 10 -10. 5 5 s = $2.55

  16. Midterm Study Guide 20) The temperature was 25 degrees Fahrenheit when Mandy awoke. The temperature dropped 4 degrees per hour. How many hours did it take for the temperature to drop to -7 degrees Fahrenheit? - 25 -25 -4 -4

  17. Midterm Study Guide 21) , find the unknown length. 1st find the corresponding sides & them up in a proportion 2nd substitute the values for each of the sides. 3rd cross product and solve the equation.

  18. Midterm Study Guide 22)A building with a height of 14 m cast a shadow that is 16 m long while a taller building cast a 24 m long shadow. What is the height of the taller building? 1st draw each figure and set up the values in a proportion. 2nd You can cross product or simplify the fraction (without the variable). 3rd solve the equation.

  19. Midterm Study Guide 23) Point H at coordinate (1,4) is rotated counterclockwise. After the transformation what quadrant will H’ be located? 1st indicate where the original point is located at (general area is fine) 2ndTurn the point to the left around origin & you will see that the point will go into Quadrant 2

  20. Midterm Study Guide 24)What are the coordinates of the reflection of the triangle over the x - axis? 1st locate the x-axis 2nd flip the figure over the x-axis, it will land in Quadrant 2 x
