Answer:
[C] -1
Explanation:
3 - 2x = 5
Subtract 3 from both sides
3 - 2x - 3 = 5 - 3
Simplify
-2x = 2
Divide both sides by -2
-2x / -2 = 2 / -2
x = -1

There might be more to this problem that not included?
Based on the question written, J and Q would be anything that is mathematically supported.
I could a virtually endless combination, that's why I think we may be missing part of the question.
Here are some solutions:
J=11, Q = 6 11-5=6
J=12, Q= 7 12-5=7
J= 7, Q = 2 7-5=2
J = 162, Q = 157 162-5=157
Using proportions, it is found that the actual cost of each pineapple is of $2.12
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, considering that the waste factor is of 15%, the<em> </em>total price<em> </em>should be of:
P = 0.85 x $14.95 = $12.7075.
For a case of 6 pineapples, hence the price of each is given by:
Pp = $12.7075/6 = $2.12.

Answer:
see below
Step-by-step explanation:
Let f = number of friends
all but one friend got 6 pieces and 1 friend got 2 for a total of 50 pieces
6(f-1) + 2 = 50
Subtract 2 from each side
6(f-1) +2-2 = 50-2
6(f-1) = 48
Divide by 6
6(f-1)/6 = 48/6
f-1 = 8
Add 1 to each side
f-1+1=8+1
f=9

Answer:
x = 40
Step-by-step explanation:

=> 5x = 1100 - 900
=> 5x = 200
=> x = 40
