Chapter SR10, Problem 18P

Solution

To write an algebraic expression that represents the number of miles Steve drove.

  $5x$

Given:

Steve drove x miles per hour for 5 hours.

Concept Used:

• The term more indicates the addition operation.
• The term less/reduced is used for subtraction.
• The term times indicates the product.
• The term quotient represents the division.

Calculation:

Since he drove 5 hours at a rate of x miles per hour, the total number of miles drove can be obtained by multiplying the speed with the time.

So, the algebraic expression that represents the number of miles drove is given by $5\cdot x\text{ or }5x$ .

Thus, the algebraic expression for the given phrase is $5x$ .
