9514 1404 393

Answer:

  • Alvin: 37
  • Elga: 49

Step-by-step explanation:

Let 'a' and 'e' represent Alvin's and Elga's ages, respectively.

  a = e-12 . . . . . Alvin is 12 years younger

  a + e = 86 . . . the sum of their ages is 86

__

Substituting for 'a' gives ...

  (e -12) +e = 86

  2e = 98

  e = 49

  a = 49 -12 = 37

Alvin is 37; Elga is 49.

Figure a’b’c’d’f is a dilation or figure abcdf by a scale factor of 1/2. The dilation is centered at (-4,-1)
AfilCa [17]
B is true.

A dilation creates similar figures.  By definition, the proportion of the sides of similar figures is the same.  AB/A'B' would be the same as BC/B'C', since the numerator of both comes from the first figure and the denominator of both comes from the second figure.
