Answer:

x = 2

y = 4

Step-by-step explanation:

<em><u>Since it gives you the "value" of y, just plug one of them into an equation:</u></em>

y = x + 2

3x - 2 = x + 2

<em><u>Now, subtract x from both sides:</u></em>

3x - 2 = x + 2

-x         - x

__________

2x - 2 = 2

<em><u>Then, add 2 to both sides:</u></em>

2x - 2 = 2

    + 2  + 2

________

2x = 4

<em><u>Finally, divide both sides by 2:</u></em>

2x = 4

x = 2

<em><u>Now to get y, just plug in 2 for x in an equation:</u></em>

y = x + 2

y = 2 + 2

y = 4

a gas company in massachusetts charges $1.30 for 16.7 ft3 of natural gas. convert this rate to dollars per liter of gas
Katyanochek1 [597]

By using a change of units, we can see that the rate in dollars per liter is:

R = $0.0027 per liter.

<h3>How to convert the rate?</h3>

Here we have a rate in dollars per cubic foot, and we want to rewrite this in dollars per liter. So we just need to apply a change of units.

The original rate is in dollars per square foot, and it is given by:

R = $1.30 for 16.7ft^3

We know that the relation between cubic feet and liters is:

1ft^3 = 28.32 L

Then, if we apply a change of units, we can rewrite the volume as:

16.7ft^3 = 16.7*(28.32) L = 472.9 L

Then the rate is $1.30 per 472.9 L, taking the quotient we get:

R = ($1.30/472.9 L) = $0.0027 per liter.
