He had walked 8 blocks, and that was 25% (or .25) of the distance to the school. Let’s let “D” represent the total distance... D x .25 = 8 blocks Divide both sides of the equation to solve for D... D = 8 / .25 = 32 So the total number of blocks to his school is 32.
The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . ... If coordinates of any two points of a line are given, then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.Apr 15, 2018
