6(2a+3b-c)
The correlation coefficient (r) is a number that describes how closely the numbers in the data set are related. The correlation coefficient will always be between −1.0 and +1.0. If the correlation is positive, there is a positive relationship. If it is negative, the relationship is negative. If the two are not correlated at all, the correlation coefficient will be 0. Strong and weak correlations are a little more subjective in that there is no exact cutoff between strong and weak, but generally, any r value that is close to either 1 or negative 1 is considered strong. Any value of r that is closer to 0 is considered weak.
$2x + $1.5y = 12 packages
$2(4) + $1.5(8)
$8+$12 = 12 packages
$20 for 12 packages if you buy 4 packages of hamburger buns, and 8 packages of hot dog buns
Answer:
the real question is why does sarah neighbor want shark teeth?
Step-by-step explanation:
8 + 4 (2x+7) = 2 (2+6x), 4 (2x+7) + 8 = 2 (6x+2), (4 x 2x + 4x7) + 8 = 2 (6x+2)
x = 9
