Expand 8(5-r)/5=-2r as indicated: 40 - 8r
----------- = - 2r
5
Multiply both sides by 5, obtaining 40 - 8r = - 10r
Combine like terms: 40 = - 2r
Divide both sides by -2: -20 = r
The solution to 8(5-r)/5=-2r is -20. Verify this by subbing -20 for r in the given equation.
The correct answer would be C., I believe, because you take the opposite of the coordinate and subtract one. Hope this was helpful! (:

Step-by-step explanation:
<h3>
The missing data is: " The cost of renting a conoe to use on River Y costs $28. The cost of renting a conoe to use on River Z costs $3 per hour plus a $13 deposit".</h3>
Let's find the first equation.
You know that the cost of renting a conoe to use on River Y costs $28. This is:

To find the second equation you need to remember the Slope-Intercept form of a Linear equation. This is:

Where "m" is the slope and "b" is the y-intercept.
Since the cost of renting a conoe to use on River Z costs $3 per hour plus a $13 deposit, you can identify that:

Therefore, the equation that represents this situation is:

So, the System of equations that could be used to find the total cost "c" of renting a canoe for "n" hours, is:
