Answer:
18
Step-by-step explanation:
50 - 32 = 18
125,594 miles. Canada coastline (x) - U.S. Coastline (12,383) = 113,211.
x - 12,383 = 113,211
x - 12,383 + 12,383 = 113,211 + 12,383 (by addition property of equality)
x = 113,211 + 12,383
x = 125,594
Basically, you add the two given numbers together.
$100 - $61
$39 (how much you need for the price to become equal)
$15 - $12
$3 (how much cheaper it is per uniform)
$39/$3
13 uniforms is where it is equal
14 uniforms is where it is a better deal
1. The coefficient of x is the constant of variation. It is 40.
2. -12 = -2*6 . . . . . you know this because you know your times tables
.. f(x) = -2x
How do we know theres got to be more
