Answer:
5 gallons of water must be added.
10 gallons to start with
adding 'x' gallons of water final volume = 10 + x
.9 (10) = amount of vinegar
.1(10) = amount of water
amount of vinegar before and after water addition is constant
.9(10) = .6(10+x)
9 = 6 + .6x
3 = .6x
x = 5 gallons of water to be added

Answer:
30 ounces
Step-by-step explanation:
You first have to write out the two equations:
5+0.25x=y
2+0.35x=y
Then simply equal the equations to each other:
5+0.25x=2+0.35x
Subtract the 2 from both sides:
3+0.25x=0.35x
Subtract the 0.25x from both sides:
3=0.10x
Divide the 0.10 on both sides:
30=x
So, 30 ounces is your answer!
You can check by plugging 30 back into the equations to make sure that they are equal to each other.
5+0.25(30)=12.5
2+0.35(30)=12.5
Answer:
Initially:
Cam has X stickers.
Dan has 2x.
Dan gives Cam 15 stickers:
Cam has x + 15 stickers.
Dan has 2x - 15 stickers.
2x - 15 = (x + 15) + 22.
X = 52 stickers.
x + 15 = 52 + 15 = 67 stickers.
2x - 15 = 2*52 - 15 = 89 stickers.
