Question

andrea is three times older than eliza. suzie is 4 years older then eliza. if eliza's age can be represented by x, create an expression that represents the combined age of all three girls

Answer 1

Combined age = 5x+4 years

Explanation:

let Eliza's age be x

given that Andrea is three times older than Eliza, hence Andrea's age is

= 3x years

it is also given that Suzie is 4 years older than eliza, hence Suzie's age is

= (x + 4) years

Therefore the combined age

= Eliza's age + Andrea's age + Suzie's age

= x + 3x + (x+4)

= x + 3x + x + 4

= 5x + 4
