Three friends recorded, in different units, the lengths of the hopscotch paths they made.
ivann1987 [24]

From the options given, Dustin's hopscotch path was the longest in comparison to the other two friends.

<h3>How to find out who had the longest path?</h3>
  • Make sure all distances use the same units.
  • If necessary convert the distances.
  • Compare the distances.

Based on this, let's make sure all distances are in feet.

  • Cassey: 94 feet

  • Jasmin: 1100 in or 91.66 feet
  • Each inch is equivalent to 0.0833
  • 1100 x 0.0833 = 91.66

  • Dustin: 32 yards or 96 feet
  • 1 yard = 3 feet
  • 32 x 2 = 96 feet

Based on this, the person with the longest path is Dustin.

qaws [65]

Answer:

You aren't supposed to add 3k

Step-by-step explanation:

3k is a positve number. So instead of adding you have to subtract to be able to move on. Correct way shown below. Once you get this step wrong your answer will also be wrong. At the end you also need to divide

19-2k= 3k-1

  -3k  -3k

19-5k= -1

-19      -19

 -5k= -20

-5/-5= -20/-5

    k=4
