Respuesta :

Answer:

2-1/2x=m

Step-by-step explanation:

Jill:2

Beth:1/2x

Meg:m

Answer:

  • j = m-2
  • b = m/2

Step-by-step explanation:

The relationships described as "the situation" are ...

  Jill is 2 year younger than Meg

  Beth is half as old as Meg

The simplest sort of expressions to write are ones that express these relationships directly. If we let j and b represent Jill's and Beth's ages (in years), respectively, then ...

  j = m - 2 . . . . . . . . Jill's age is 2 years less than Meg's age

  b = m/2 . . . . . . . . . Beth's age is half Meg's age

_____

We could get more elaborate and write expressions like ...

  m = j+2

  j +b = (3/2)m -2

  j = 2(b -1)
