Unit 1: Multi-Step Equations, Angle Relationships and Transformations. 2(4x - 3) - 8 = 4 + 2x x = 3n - 5 = -8(6 + 5n) n = -3(4x + 3) + 4(6x + 1) = 43 x = 24a - 22 = -4(1 - 6a) a = -7p - 12 = -4p + 3(-4 - p) p = A cell phone company charges $30 a month plus $.07 per min. If Mr. T's January cell phone bill was $59.40, how many minutes did he talk? 420 minutes 197 minutes 1,277 minutes 848 minutes My dad and I went shopping for some new tools this weekend. He bought a few screwdrivers and several boxes of screws. The screwdrivers were $4.50 each and each box of screws was $2.50. He bought twice as many boxes of screws as screwdrivers and spent a total of $19.00. How many screwdrivers were in the set and how many boxes of screws did he buy? boxes of screws screwdrivers Name the angle relationship between angles 1 and 5. Vertical Complementary Corresponding Supplementary <b and <f are: vertical angles alternate interior angles corresponding angles same side exterior angles <e and <h are: vertical angles corresponding angles same side interior angles supplementary angles If the measure of angle a is 120 degrees, then the measure of angle d is degrees. If the measure of angle f is 70 degrees, then the measure of angle d is degrees. If the measure of angle h is 3x degrees, and the measure of angle e is 105 degrees, then x = x = x = x = x = Identify the transformation. rotation translation reflection dilation Identify the transformation. dilation translation rotation reflection Identify the transformation. reflection dilation rotation translation Give the coordinates for a reflection over the x-axis.
