Chapter 49, Problem 1AR

To determine

(a)

To express: the given problem in algebraic from.

Answer to Problem 1AR

The required algebraic expression is $\left(\text{x}\text{+}\text{y}\right)-\text{c}$.

Explanation of Solution

Given problem:

The sum of x and y reduced by c

Calculation:

We need to write the algebraic expression,

  $\begin{array}{l}\Rightarrow \left(\text{x}\text{+}\text{y}\right)-\text{c}\\ \Rightarrow \text{x}\text{+}\text{y}-\text{c}\end{array}$

Thus, the required algebraic expression is $\left(\text{x}\text{+}\text{y}\right)-\text{c}.$

To determine

(b)

To express: the given problem in algebraic from.

Answer to Problem 1AR

The required algebraic expression is $\frac{ab}{d}$.

Explanation of Solution

Given problem:

The product of a and b divided by d.

Calculation:

We need to write the algebraic expression,

  $\begin{array}{l}\Rightarrow \left(\text{a}\times \text{b}\right)\text{÷}\text{d}\\ \Rightarrow \frac{ab}{d}\end{array}$

Thus, the required algebraic expression is $\frac{ab}{d}.$
