- 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>
<span>-49 + -2x + 12x = 101 + -12x + 12x Combine like terms: -2x + 12x = 10x -49 + 10x ... 101 + 49 = 150 10x = 150 Divide each side by '10'. x = 15 Simplifying x = 15 </span><span>

Answer:
$1.25 per hot dog
Step-by-step explanation:
Keep in mind both the distance and time of the scenarios. The faster and more distance travelled = a higher gradient for the line. If he slows, the gradient decreases. If he stops, the line is flat but time still goes on.
