3*-3 = -9   Then you need to simplify -9.  -9➗ 2 = 4.5 Your final answer is 4 1/2.
    2      2                                              2                                             

Your third step is most likely when you're changing the decimal to fraction form.

Hope this is right and helpful!

3 times negative 11 is negative 33 and 3 times 2 is 6, so you have negative 33 divided by 6 and that is negative 5.5

If DF=78, DE=5x-9, and EF=2x+10, find DE.
Kazeer [188]

Given that E is a point between Point D and F, the numerical value of segment DE is 46.

<h3>What is the numerical value of DE?</h3>

Given the data in the question;

  • E is a point between point D and F.
  • Segment DF = 78
  • Segment DE = 5x - 9
  • Segment EF = 2x + 10
  • Numerical value of DE = ?

Since E is a point between point D and F.

Segment DF = Segment DE + Segment EF

78 = 5x - 9 + 2x + 10

78 = 7x + 1

7x = 78 - 1

7x = 77

x = 77/7

x = 11

Hence,

Segment DE = 5x - 9

Segment DE = 5(11) - 9

Segment DE = 55 - 9

Segment DE = 46

Given that E is a point between Point D and F, the numerical value of segment DE is 46.
