Answer:

Step-by-step explanation:
Find two numbers whose quotient is -1 and the subtraction of the first minus the second is -3/2
Let two numbers are x and y. When they are divided the quotient is -1. So,

It can also be written as :
x = -y ....(1)
The subtraction of first minus the second is -3/2
.

Use equation (1) in (2),

From equation (1) : 
Hence, two numbers are

3 baseball cards = $160
first card + (second card + third card) = $160
first card = second card + third card
$160 ÷ 2 = $80
thus the first card was $80
A proportional relationship would look like y=mx (no y-intercept).
The formula for temperature Fahrenheit involves an offset (y-intercept); this is one reason I claim that the relationship in question is NOT proportional.
