1: y=-2
2:x=1
These should be the answers unless these are two parts of the same question
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.
Hope this helps!

Answer:
A computer parts company wants to make a rectangular memory board that has a perimeter of 28 centimeters and a diagonal length of 10 centimeters. Find the dimensions of the board. Consider the length to be the longer side.: Call the two sides L & W: the perimeter 2L + 2W = 28 Simplify, divide by 2 L + W = 14 L = (14-W); use this form for substitution
