Let Abby's father's age be x.
Then Abby's age = 1/2 x or her father's age= 2* Abby's age
Abby's brother's age = 9 years
So, Abby's age= 2*9= 18 years
∴ her father's age = 2*18 =36 years

Which value of p makes the equation 18+ 2 (3p – 8) = –37 true?
Volgvan

Answer:

p = -6.5

Step-by-step explanation:

<u>Given:</u>

  • 18+ 2 (3p – 8) = –37

<u>Solving for p:</u>

  • 18+ 2 (3p – 8) = –37
  • 18 + 6p - 16 = -37
  • 6p + 2 = -37
  • 6p = -37 - 2
  • 6p = -39
  • p = -39/6
  • p = -6.5

Option 2 is correct in the list
