The sum of the age of the father and son is 44 years. After 8 years , the age of the father will be twice the age of the son .Find the present ages.

x = age of the son

y = age of the father

x + y = 44

y = 2x

Substitute our second equation into our first equation.

x + 2x = 44. Combine the like terms.

3x = 44. Divide each side by 3

x = 44/3 or 14.7.

Substitute 44/3 into x for our second equation to find y

y = 2(44/3). Multiply 2 by 44/3

y = 88/3 or 29.3

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
