−3/4+(1/10÷2/5)
parenthesis first
1/10 divided by 2/5
copy dot flip
1/10 * 5/2
5/20
1/4
−3/4+(1/10÷2/5)
-3/4 + 1/4
-2/4
divide top and bottom by 2
-1/2
if in total Kasey has 8 packaged of gelatin and it takes 1 1/3 for each mold which equals 6 servings than you could work it out as
8 divided by 1 1/3=6.015 since its not a whole number than you'd want to go down to just 6 resulting in Kasey creating 6 molds
6 molds times 6 servings= 36 servings
Take the equations and solve them. they should lead up to degrees. Then add those degrees together and subtract that answer by 360 degrees and that should be your answer.
Hope this helps
Answer:


Step-by-step explanation:
Given


Solving (a): The earnings.
This is calculated as:



Solving (b): New Value
This is calculated as:
So, we have:



Rule: If x-k is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem.
Using that rule, we can see that x+5 is really x-(-5) so k = -5.
Therefore,
p(k) = 0
p(-5) = 0
so the answer is choice D.
