Answer:
first we'll have to do it in order which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)
Step-by-step explanation:
(22÷2-2.5)+(4-6+6)
(11-2.5)+(4-6+6)
(8.5)+(4)
= 12.5

Answer: Sometimes true</h3>
========================================================
Explanation:
-8+d is positive only when d > 8
Here's why
-8+d > 0
-8+d+8 > 0+8 .... add 8 to both sides
d > 8
So if Jessica said "d is greater than 8", then her claim would always be correct.
However, her claim is sometimes true.
Two counter examples could be when d = 1 and d = 2.
If d = 1, then -8+d = -8+1 = -7 which isn't positive.
If d = 2, then -8+d = -8+2 = -6 which also isn't positive.
Basically if d is anything smaller than 8, then you'll have -8+d be negative.
If d is something larger than 8, say d = 9, then -8+d = -8+9 = 1 which is finally positive.

You can add $2.55 three times; or you can multiply $2.55 times 3. Either way you will have the answer of $7.65 as your total.
I hope that helped you. (:
If she cuts it then the angle would become a right angle so it sould be 90º
