Answer:

Step-by-step explanation:
Given

(a): Write as additive inverse.
An additive inverse is of the form a + (-b)
In this case:


So, the expression can be represented as:

(b): Number line representation
When the expression in (a) is solved.
The result is:

This means that the number line must accommodate 7 and -1.
Having said that, options (b) and (c) are out because their range is 0 to 15 and this excludes -1.
Option (d) is a wrong representation of 
Hence, (a) is correct

Answer:
because this is a parallelogram
=> b - 10 + b + 10 = 180
<=> 2b = 180
=> b = 90
with b = 90 => b - 10 = 80
b + 10 = 100
we also have:
d = b + 10 => d = 100
c = b - 10 => c = 80
