Answer:

Step-by-step explanation:

10x - 15y = 21

15y = 10x - 21

y = ⅔x - 7/5

slope of line is ⅔

slope of any perpendicular to line is -3/2

y = kx + k

slope of line is k

k = -3/2

Find the missing value 3/8 = _____ to 72
Morgarella [4.7K]

Answer:

27

Step-by-step explanation:

First, you need to find the factor that coverts 8 to 72. I look as these problems as 3 to x and 8 to 72. To do this, divide 72 by 8, and that's what you'd multiply 3 with.

72/8 = 9

9 x 3 = 27
