Given:
The ratio of the number of Rs2 coins to the number of Rs5 coins is 1:3.
The value of all the Rs5 coins is Rs45.
To find:
The value of all the Rs2 coins in the box.
Solution:
Let x be the number of Rs2 coins and y be the number of Rs5 coins.
The value of all the Rs5 coins is Rs45.
The ratio of the number of Rs2 coins to the number of Rs5 coins is 1:3.
Multiply both sides by 9.
The value of all the Rs2 coins in the box is:
Therefore, the value of all the Rs. 2 coins in the box is Rs. 6.

Using the change of subject of formula, the high temperature value for the day can be modeled using the expression <em>High temperature = Low temperature - 17°F</em>
<u>Giveb</u><u> </u><u>the</u><u> </u><u>Parameters</u><u> </u><u>:</u>
- <em>Low</em><em> </em><em>temperature</em><em> </em><em>=</em><em> </em><em>51</em><em>°</em><em>F</em>

High temperature = Low temperature - 17°F
Therefore, the equation which models the high temperature is : <em>High temperature = Low temperature - 17°F</em>
