Chapter 1.3, Problem 35E

To determine

To calculate : the value of the expression $\frac{6.5y+2}{x+2}$ when $x=4and\text{ y}=3$

Answer to Problem 35E

The value of the expression $\frac{6.5y+2}{x+2}=3.583$ when $x=4and\text{ y}=3$

Explanation of Solution

Given information :

Consider, the expression,

$\frac{6.5y+2}{x+2}$

when $x=4and\text{ y}=3$

Calculation :

To evaluate the value of the expression, substitute, $x=4and\text{ y}=3$

Therefore,

The value of the expression is obtained as:

  $\begin{array}{l}\frac{6.5y+2}{x+2}=\frac{6.5\times 3+2}{4+2}\\ \frac{6.5y+2}{x+2}=\frac{19.5+2}{4+2}\left[\text{multiply}\right]\\ \frac{6.5y+2}{x+2}=\frac{21.5}{6}\left[\text{add}\right]\\ \frac{6.5y+2}{x+2}=3.583\left[\text{divide}\right]\end{array}$

Hence,

The value of the expression, $\frac{6.5y+2}{x+2}=3.583$ when $x=4and\text{ y}=3$
