Allen's work is not written properly so I have rearranged it as shown below:
Original problem) –8.3 + 9.2 – 4.4 + 3.7.
Step 1) −8.3 + 9.2 + 4.4 + 3.7 Additive inverse
Step 2) −8.3 + 4.4 + 9.2 + 3.7 Commutative property
Step 3) −8.3 + (4.4 + 9.2 + 3.7) Associative property
Step 4) −8.3 + 17.3
We can see that in step 1), Allen changed -4.4 into +4.4 using additive inverse. Notice that we are simplifying not eliminating -4.4 as we do in solving some equation. Hence using additive inverse is the wrong step.
Alen should have collect negative numbers together and positive numbers together.
Add the respective numbers then proceed to get the answer.
–8.3 + 9.2 – 4.4 + 3.7
= –8.3 – 4.4 + 9.2 + 3.7
= -12.7 + 12.9
= 0.2
Given:
A right angle triangle with angles 45, 45, 90 degrees.
Hypotenuse of the triangle = 
mm
Base of the triangle = t
To find:
The value of t.
Solution:
In a right angle triangle,
Using this trigonometric ratio in the given triangle, we get
Therefore, the value of t is 7 millimetres.

Answer:
x=25/2
Step-by-step explanation:
8-2x-8=-17-8
-2x=-25
-2x/2= -25/2
