Solve the following problem. Be sure to show all steps (V. E.S. T.) and work in order to receive full credit. The sum of three numbers is 26. The second number is twice the first and the third number is 6 more than the second. Find the numbers.

The numbers are 4, 8 and 14

Step-by-step explanation:

Required

Determine the three numbers

We start by declaring the variables

Let the three numbers be

Next, we write the relationships between the numbers

--- Second = Twice the first

--- Third = 6 more than second

--- Sum of the three numbers

Then, we solve for each number

Substitute 6 + y for x in

Collect Like Terms

Substitute 2 * x for y in

Solve for x

Recall that:

Recall that:

Hence, the numbers are 4, 8 and 14

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
