Chapter 3: Q2. (page 118)

Write an equivalent expression of 9(x-4).

Short Answer

Expert verified

The equivalent expression is 9x-36.

Step by step solution

01

Step 1. Apply the concept of distributive property

In this type of question, apply the concept of distributive property which means a(b+c)=ab+bc.

02

Step 2. Finding the equivalent expression

Since, the expression is 9(x-4).

Now, apply the distributive law a(b+c)=ab+bcin the above expression to get the solution,

=9(x−4)=9×x−9×4=9x−36

Driving A family is driving to Houston, Texas. A sign indicates that they are 700 miles from Houston. Their car’s trip odometer indicates that they are 400 miles from home. They are travelling at an average speed of 60 miles per hour.

  1. Write an expression for the distance (in miles) they will be from Houston in x hours.
  2. Write an expression for the distance (in miles) they will be from home in x hours.
  3. Use the expression from parts a and b to write and solve an equation to find the number of hours they will drive until they are exactly halfway between Houston and their home.
  4. Suppose they travel by local roads instead of highway. They travel the 700 miles at a speed of 45 miles per hour. How long will they drive before they are exactly halfway between Houston and their home?
