Algebra 1 Chapter 1

∣ 2x + 9 ∣ = 15

• x = 3 

• x = 3
  x = -6

• x = 3
  x = -12

• x = 6
  x = -12

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step

• They should add 19 instead of subtracting 19

• I can not find an error

• Instead of adding 3k they should subtract 3k

Angela gets paid a flat rate of $15.00 to mow her neighbors lawn plus an additional $3 per hour to rake the leaves. The money she earns is represented by the equation m=3h+15, where m represents the amount of money she earns (in dollars) and h is the number of hours she rakes leaves for. Which of the following equations can be used to find h, the number of hours she rakes leaves for?
