Answer:

No, she's incorrect. 4x - 5.2y + 6y + 7.9x - 8x = 3.9x + 0.8y

Step-by-step explanation:

To find out if Esme is correct, we have to group the like terms and simplify.

  • [tex](4x+7.9x-8x) + (-5.2y+6y)[/tex]
  • [tex]3.9x+0.8y[/tex]

As you can see, 3.9x + 0.8y is the correct simplified expression, thus making Esme incorrect.
