First you need to get the unit rate by dividing 715 by 13, getting 55 miles per hour. You then will need to divide 495 by 55 to get the answer of 9
15*6=90 hours
90 *8.25=742.50
Your answer would be $742.50. Hope it helps!
Answer:
The first number is 138.
Step-by-step explanation:
Let the first number be <em>x.</em>
<em />
Then since they are consecutive numbers, the second number will be (<em>x</em> + 1), the third (<em>x</em> + 2), the fourth (<em>x</em> + 3) and the fifth being (<em>x</em> + 4).
We are given that their sum is 700. Therefore:

Solve for <em>x</em>. Combine like terms:

Subtract 10 from both sides:

Divide both sides by five. Therefore:

The first number is 138.
A
It is the first one
