Answer:
1. 5x + 5*2 = 30
2. 5x + 2 = 27
Step-by-step explanation:
It is D) 153.86 just find it by using the formula
By the method of writing the obvious answer,
(3, -2)
- 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>
