scoundrel [369]

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

$p*v=k$

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

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

substitute in the equation

$(2.2)*v=320$

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

The sum of 45% of a number and 55% of the same number is 200. what is the number?

Ymorist [56]

.45x+.55x=200
Combine like terms
1x=200
So x is 100

Or you can do 45%+55%=100%
And 100% of 200 is 200

Which of these is a simplified form of the equation 15x + 4 = 5 + 3x + 1x? (2 points)

Mars2501 [29]

Answer:

11x=1

Step-by-step explanation:

15x+4=5+3x+1x Bring everything with an x in front of it to the left side

15x-3x-1x+4=5 Simplify the x values

11x+4=5 Bring the 4 to the right side

11x=5-4

11x=1
