- Revathi's age is 1/3 of her mother's age. If their difference in age is 24 years, find Revathi's age.

Given,
- Mother's age = x
- Revathi's age = 1/3 x = ?
- Difference in their age = 24 years ⇨ x - 1/3 x = 24.
Now, let's solve this question using the above equation which we just formed.

Combine x and
to get
.

Multiply both sides by
, the reciprocal of
.

Express
as a single fraction.

Multiply 24 and 3 to get 72.

Divide 72 by 2 to get 36.

We now have the age of Revathi's mother (x) = <u>36 years</u>. Now, let's find Revathi's age ⇨ 

- So, Revathi is <em><u>1</u></em><em><u>2</u></em><em><u> </u></em><em><u>years </u></em><em><u>old.</u></em>
A triangle is 180°. So you can do:
3.2n + 6.4n + 2.4n = 180 Simplify
12n = 180
n = 15 Now that you know the value of n, you can plug it into each individual angle/equation
∠X = 3.2n plug in 15 for n
∠X = 3.2(15)
∠X = 48°
∠Y = 6.4(15)
∠Y = 96°
∠Z = 2.4(15)
∠Z = 36°
Answer:
Step-by-step explanation:
(0, -9) and (3,3)
(3+9)/(3-0) = 12/3 = 4
y + 9 = 4(x - 0)
y + 9 = 4x - 0
y = 4x - 9
