Tyler is 9 years old his sister olivia is 6 years less than twice his age write a numerical expression for olivia’s age

Okay so Tyler is 9 right? and his sister is 6 years less than TWICE of his age. so twice of his age is 18. (9 x 2 = 18) and she is 6 years less (18-6 =??) thus, Olivia is 12. a way you can write an expression is:

(9 x 2) - 6 = 12.

fyi: parentheses means you do whatever equation that in in the parentheses first.

hope I helped! Good Luck!
