If DF = 170, find the value of x. Then find DE and EF.<br> DE=3x + 20<br> EF=2x + 40
Julli [10]

9514 1404 393

Answer:

  DE = 86

  EF = 84

Step-by-step explanation:

We assume that point E lies on segment DF, so that ...

  DE + EF = DF

  (3x +20) +(2x +40) = 170

  5x = 110 . . . . . . . . . . . . . . . collect terms, subtract 60

  x = 22 . . . . . . . . . . . . divide by 5

  DE = 3×22 +20 = 66 +20 = 86

  EF = 2×22 +40 = 44 +40 = 84

IrinaVladis [17]

Answer:

<em>The brand name television's dimensions are 32 inches by 64 inches.</em>

Step-by-step explanation:

<u>Scaling</u>

Jason is considering two similar televisions at a local store. The sizes of the generic television are 3/8 the size of the brand name.

If we knew the size of the brand name television, we would have to multiply its dimensions by 3/8, but instead, we have the dimensions of the generic television, so to find the brand name television, we multiply by 8/3.

12 inches * 8/3 = 32 inches

24 inches* 8/3 = 64 inches

The brand name television's dimensions are 32 inches by 64 inches.

How many solutions does this equation have?<br><br> –10q = –10q − 7
Salsk061 [2.6K]

Answer:

None (no solutions)

Step-by-step explanation:

-10q=-10q-7 (add 10q to both sides to get the costant 7 by itself)

-10q+10q=-10q+10q-7

0=-7 ( zero will never equal -7 hence there are no solutions to this equation)
