Answer:

Option D.) 28 Pa

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

In this problem

P*V=k

step 1

Find the value of k

For P=84\ Pa,V=51\ L

substitute and solve for k

k=84*51=4,284

step 2

If the volume is expanded to 153 L, what will the new pressure be?

we have

The equation is equal to

P*V=4,284

For  V=153\ L

substitute

P*153=4,284

P=4,284/153

P=28\ Pa

What is the solution to the linear equation?
patriot [66]
Equation:  2/5 + p = 4/5 + 3/5p

Simplify Both Sides:
p + 2/5 = 3/5p + 4/5

Subtract 3/5p from both sides:
p + 2/5 - 3/5p = 3/5p + 4/5 - 3/5p

2/5p + 2/5 = 4/5

Subtract 2/5 from both sides:
2/5p + 2/5 - 2/5 = 4/5 - 2/5

2/5p = 2/5

Multiply both sides by 5/2

(5/2) * (2/5p) = (5/2) * (2/5)

p  =  1


Answer:  p  =  1





Hope that helps!!! (Answer:   Letter Choice (A),  p  =  1
