Given the <em>quantities</em> of powdered milk and whole wheat to prepare a batch of pancakes, we can determined the <em>total</em> amount of each ingredient by simple rule of three:

Powdered milk

$x = 4\,batches\times \frac{1}{4}\,\frac{cups}{batch}$

$x = 1\,cup$

Whole wheat

$y = 4\,batches \times \frac{3}{2}\,\frac{cup}{batch}$

$y = 6\,cups$

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.

Which expression represents the following word sentence? Four times the sum of 3. 2 and a number is the number less 1. 4. 4n 3.

adoni [48]

The line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given to us

Four times the sum of 3.2 and a number is the number less than 1.4

Let the number be n.

It is given that the sum of 3.2 and number,

n + 3.2

Four times the sum, therefore,

4(n+3.2)

The total we got is the number less 1. 4. thus,

4(n+3.2) = n - 1.4

Hence, the line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.
