Answer 1

Answer:

$7 + (-8)$

Step-by-step explanation:

Given

$7 - 8$

(a): Write as additive inverse.

An additive inverse is of the form a + (-b)

In this case:

$a = 7$

$b = -8$

So, the expression can be represented as:

$7 + (-8)$

(b): Number line representation

When the expression in (a) is solved.

The result is:

$7 - 8 = 7 + (-8) = -1$

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 $7 - 8$

Hence, (a) is correct
