Answer:

x = 1

y = -3

Step-by-step explanation:

We have the value of <em>x</em> in terms of <em>y</em> already, so our first step will be to plug in <em>y + 4</em> for <em>x</em> in the first equation. This gives us:

y + 4 = 2y + 7

From here, we can just solve for <em>y</em>:

y + 4 = 2y + 7\\4 = y + 7\\-3 = y

And now that we know <em>y = -3</em>, we can solve for <em>x</em> using the second equation:

x = y + 4\\x = -3 + 4\\x = 1

Lastly, we should just double check our answers using the first equation to see if they work:

1 = 2 * -3 + 7\\1 = -6 + 7\\1 = 1

It does!

Wich is greater 42% or 0.44
kakasveta [241]
Since percent means 'over 100', you can put 42 over 100: \frac{42}{100} = .42. Since .42 is less than .44, that means that .44 is your answer.

Tina uses a $50 gift certificate to buy a pair of pajamas for 17.97 a necklace for 25.49 and 3 pairs of socks that each cost the
Furkat [3]
The overall cost is $50.33. you now subtract out the prices you know. The easiest way to do that is to add them up; 17.97+25.49. That is 43.46.

The next step is to subtract 43.46 from 50.33. 50.33-43.46=6.87. That is the price of all the pairs of socks put together.

to find out how much one pair is, you then divide 6.87 by 3. That is 2.29.

The answer is $2.29

I hope this helps!
