<h3>How to determine the expression that shows how to rewrite 5 − 6 using the additive inverse?</h3>The complete question is added as an attachment
The expression is given as:
5 - 6
Put 6 in a bracket.
So, we have:
5 - 6 = 5 - (6)
Express 6 as --6
So, we have:
5 - 6 = 5 - -(-6)
Rewrite as:
5 - 6 = 5 + (-6)
The above means that the arrow on the number line must start from 5 and moves in the negative direction in 6 units

Answer:
The required specific heat is 196.94 joule per kg per °C
Step-by-step explanation:
Given as :
The heat generated = Q = 85.87 J
Mass of substance (m)= 34.8 gram = 0.0348 kg
Change in temperature = T2 - T1 = 34.29°C - 21.76°C = 12.53°C
Let the specific heat = S
Now we know that
Heat = Mass × specific heat × change in temperature
Or, Q = msΔt
Or, 85.87 = (0.0348 kg ) × S × 12.53°C
Or , 85.87 = 0.4360 × S
Or, S =
∴ S = 196.94 joule per kg per °C
Hence the required specific heat is 196.94 joule per kg per °C Answer
