Answer:
8
Step-by-step explanation:
Negative 25 minus negative 9 equals negative 16.
Negative 17 minus megative 15 equals negative 2.
-16/-2 equals 8
Answer:
This equation can be solved by using y = kx.
Since y = 25 when x = 60,
25 = 60k and if we solve for k then k= 5/12.
That means the equation we're using is
y = (5/12)x.
Plug in y = 30 and you get
30 = (5/12)x
Solve for x
30 * (12/5) = x
360/5 = x
x = 72
