Solve the equation. Check your solution.

d12+25=29

Short Answer

Expert verified

The solution for the equation d12+25=29 is d=48.

Step by step solution

01

.  Separate the variable and constants

Write the original equation and separate the variables.

d12+25=29d12=29−25d12=4

02

.  Solve for d

Now, multiply both sides of the equation by 12.

Therefore, the solution of the equation is d=48.

d12×12=4×12d=4×12d=48

03

.  Check the solution 

To check the solution, write the original equation and substitute the value of d.

d12+25=29

Now, substitute d=48and check the result.

4812+25=294+25=2929=29

As the left-hand side is equal to right hand side, this signifies that the solution is correct.

The length of a rectangle is 5 feet less than twice its width. The perimeter of the rectangle is 38 feet. Let w represent the width. Write an equation for the perimeter of the rectangle in terms of w. Then solve the equation to find the length and width of the rectangle.

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?
