Answer:
A - PV/RT = n
Step-by-step explanation:
The objective is to isolate the variable n which represents moles. To do so, you must get rid of the surrounding variables.
Surrounding n, the variables R (gas constant) and T (temperature) are shown being multiplied with n. To get rid of them, you must do the inverse which is to divide.
PV = nRT
Divide both sides by R
PV/R =nT
Divide both sides by T
PV/RT = n
And now, the variable n has been isolated and the new equation to solve for moles is presented.

Answer:
The value on the In side: 2
The first value on the Out side: 87
The second value on the Out side: 93
Step-by-step explanation:
First, I started by finding the differences by each step on both sides. I noticed that they increased together. 45-27 is 18, and it mirrored on the other side. 27-9 is 18, and it mirrored. By this I mean that 81-63=18 as well as 63-45=18. So I followed this pattern 45-38=7, so 9-7=2, and that gives us our first answer. 51-45=6, so 81+6=87, gives us our second. 57-51=6, so 87+6=93, and this gives us our third.
Answer:
Step-by-step explanation:
Yes, F(x)=7-2x is a polynomial function for which the sole x term has the exponent 1 and the constant term has the exponent 0:
F(x) = -2x^1 + 7x^0
As is true of all polynomial functions, the exponents are all positive integers (plus that of the constant term is zero).
