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.

Answer:
slope: -1/6
Step-by-step explanation:
to find the slope of a line we can use the formula (y2-y1)/(x2-x1)
this means ththe second y subtracted by the first year divided by the second x subtracted by the first x
when plugged in you get (10-8)/(-7-5)
when simplified it becomes 2/-12 and then -1/6
Not necessarily. For example, you can have a rectangle whose dimensions are 12 and 6. Length is 12 and 6 is the width.
The area (length × width) of the rectangle will be 72.
The perimeter of the rectangle (2l + 2w) will be 36.
So, in this case, the area was double the perimeter and the perimeter was not greater than the area of the shape.
