Siw is a fourth as old as mother, and Mona is a fifth as old as mother. Mother is 22 years older than the two girls together. How old are they?

Siw's age is 10 years old

Mona's age is 8 yers old

Mother's age is 40 years old

Step-by-step explanation:

Let

x ----> Siw's age

y ---> Mona's age

z ---> Mother's age

we know that

Siw is a fourth as old as mother

so

----> equation A

Mona is a fifth as old as mother

so

----> equation B

Mother is 22 years older than the two girls together.

so

----> equation C

substitute equation A and equation B in equation C

solve for z

Multiply by 20 both sides to remove the fraction

Find the value of x

Find the value of y

therefore

Siw's age is 10 years old

Mona's age is 8 yers old

Mother's age is 40 years old

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
