Answer:
x = 30
Step-by-step explanation:
-6 + 24 = x - 24 + 24
x = 24 + 6 - 24 - 24
x = 30 - 0
x = 30
The number of grams is 20 grams
Let x represent how many grams of a 15 percent alcohol solution
15%x+30%.40/x+40
=25%
0.15x+0.4.30=0.25 (x+40)
0.15x+12=0.25x+10
0.15x-0.25x=10+12
-0.1x=-2
x=-2/-0.1
x=20
Inconclusion The number of grams is 20 grams

Answer: No, it does not matter.
Step-by-step explanation:
In addition the order does not matter, this is because of the commutative property of the addition, that says that: A + B = B + A
and the associative property, that says that:
A + (B + C) = (A + B) + C
for example, if you have 4 chips and your friend gives you her 5 chips, now you have a total of 4 + 5 = 9 chips.
The case is the same if you have 5 chips and your friend gives you 4 chips, now you have 5 + 4 = 9 chips.
Other example is that:
5 chips + ( 2chips + 1 chip) = 5 chips + 3 chips = 8 chips
(5 chips + 2 chips) + 1 chip = 7 chips + 1 chip = 8 chips
You can see that the order does not matter.
