Answer:
6.3
Step-by-step explanation:
First off, we need the distance formula, which is:
If we plug in the points, we get:
If we simplify everything under the square root, we get:
In decimal, the answer is 6.3
Hint:
(2x+50) + 3x + 90 = 180
Solve for x first.
Then plug x into 2x + 50 and 3x.
Whichever gives you the smaller number is the answer.

Step-by-step explanation:
Use Distributive Property and Simplify
9x3 =27
9x3t = 27t
27t-2t =25t
Equation so far: 27 + 25t
Next Pair of Perentheis
-10x8t =(-80t) (Remeber a Negative time a positive is still a negative)
-10xs =(-10s)
Put it all together and your answer is;
27

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
