Answer:

The volume of the gas is $145.45\ cm^{3}$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

v------> the volume of a gas in cubic centimeters

p-----> the pressure of the gas in liters per square centimeters

so

$p*v=k$

we have

$v=16\ cm^{3}, p=20\ l/cm^{2}$

substitute and solve for k

$k=16*20=320$

The equation is $p*v=320$

Find the volume of the gas when the pressure is 2.2 L/cm2

so

For $p=2.2\ l/cm^{2}$ Find the value of v

substitute in the equation

$(2.2)*v=320$

$v=320/2.2=145.45\ cm^{3}$

Solve for a. 1/3(21−3a)=6−a

Tems11 [23]

1/3(21-3a)=6-a
I simplified the equation to the form, which is simple to understand
1/3(21-3a)=6-a
Simplifying:
 + 0.333333333333*(21-3a)=6-a
Reorder the terms in parentheses
+(+7-1a)=6-a
Remove unnecessary parentheses
+7-1a=+6-a
We move all terms containing a to the left and all other terms to the right.
-1a+1a=+6-7
We simplify left and right side of the equation.
a=-1
0=-1
The left and right sides are not equal, therefore there is no solution. This equation is invalid
Hope this helped

Jagroop is building a dock at his cottage. The length of the doc is 3 times the width, plus 2. Determine a simplified expression

MissTica

Answer:

Step-by-step explanation:

Let length = y width = x

y = 3x + 2

Perimeter = Sum of all sides (or sum of both lengths and both widths)

2y + 2x

2(3x + 2) + 2x
