Distribute the 2 to get the pink box
10x + 2y = 18
Then if we are subtracting the bottom equation from the pink box
10x + 2y = 18
-(10x -7y = -18)
9y = 36
y = 4
Answer:
410,000
Step-by-step explanation:
exact answer is 412,638
-8a^8b^-2/10a^-4b^-10
= (-8/10) a^(8+4)b^(-2+10)
= -4/5 a^12 b^8
=-4 a^12 b^8 / 5
Answer is A.) -4 a^12 b^8 / 5
Answer:
60.0 L
Step-by-step explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is gas constant,
and T is absolute temperature.
Since n and R don't change:
P₁V₁ / T₁ = P₂V₂ / T₂
(1.08 atm) (50.0 L) / (25 + 273.15 K) = (0.855 atm) V / (10 + 273.15 K)
V = 60.0 L
