Andhra Pradesh Board Solutions for Chapter: Linear Equation in Two variables, Exercise 6: EXERCISE - 6.3

When Rupa was born, her father was $25$ years old. Form an equation and draw a graph for this data. From the graph, find the age of the father when Rupa is $25$ years old.

When Rupa was born, her father was $25$ years old. Form an equation and draw a graph for this data. From the graph, find Rupas age, when her father is $40$ years old.

An auto charges $₹15$ for first kilometre and $₹8$ for each subsequent kilometre. For a distance of $x \mathrm{km}$, an amount of $₹y$ is paid. Write the linear equation representing this information and draw the graph. With the help of graph find the distance travelled, if the fare paid is $₹55$. How much would have to be paid for $7 \mathrm{km}$.

A lending library has fixed charge for the first three days and an additional charge for each day thereafter. John paid $₹27$ for a book kept for $7$ days. If the fixed charges be $₹x$ and subsequent per day charges be $₹y$, then write the linear equation representing the above information and draw the graph of the same. From the graph, if the per day charge is $₹4$, find the fixed charge.

In countries like the USA and Canada temperature is measured in Fahrenheit whereas in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius $\mathrm{F}=\left(\frac{9}{5}\right)\mathrm{C}+32$

Draw the graph of above linear equation having Celsius on x-axis and Fahrenheit on y-axis.

In countries like the USA and Canada temperature is measured in Fahrenheit whereas in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius $\mathrm{F}=\left(\frac{9}{5}\right)\mathrm{C}+32$

 If the temperature is $30°\mathrm{C}$, what is the temperature in Fahrenheit?

In countries like the USA and Canada temperature is measured in Fahrenheit whereas in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius $\mathrm{F}=\left(\frac{9}{5}\right)\mathrm{C}+32$

If the temperature is $95°\mathrm{F}$, what is the temperature in Celsius?

In countries like the USA and Canada temperature is measured in Fahrenheit whereas in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius $\mathrm{F}=\left(\frac{9}{5}\right)\mathrm{C}+32$

Is there a temperature that has numerically the same value in both Fahrenheit and Celsius? If yes find it?
