Question

Tyler is 8 years old.His sister Olivia is 4 years less than twice his age.Write a numerical expression to fine Olivia's age

Answer 1

Answer:

O = 2(8) - 4

Step-by-step explanation:

Age of Tyler is = 8 years

Age of Olivia is 4 years less than twice his age.

Let the age of Olivia be 'O'

Twice of Tyler's age = 2(8)

4 years less than twice his age = 2(8) - 4

Now the expression will be

O = 2(8) - 4

O = 16 - 4

O = 12 years

Answer 2

O = 8*2 - 4 = 12. Olivia is 12 years old.
