Correlation coefficient is the numerical representation of how one variable predicts the change of the other. In this case, if the AP tests scores and the SAT scores have 0.93 correlation coefficient, this means that the two results move in the same direction. When AP test results go up, then we can say that SAT scores will go up too, same also if one goes down, so does the other.
-3|2x + 6| = -12
|2x + 6| = -12/-3 = 4
2x + 6 = 4 and 2x + 6 = -4
2x = 4 - 6 = -2 and 2x = -4 - 6 = -10
x = -2/2 = -1 and x = -10/2 = -5
x = -1 and x = -5

1 yard = 36 inches
The fraction (1 yard / 36 inches) has a numerator and denominator
that are equal. So the fraction is equal to ' 1 ', and we can multiply
(26 inches) by it without changing any value. That'll change the units
of the '26 inches' to 'yards', which is exactly what we need.
(26 inches) x (1 yard/36 inches) = (26/36) yard
That's 13/18 yard, or 0.7222... yard.
