A cafe only sells two types of sandwiches, turkey and steak. The cafe charges $4 for turkey sandwiches and $6 for steak sandwich

valkas [14]

Answer:

513 turkey sandwiches were sold.

Step-by-step explanation:

Let's use $x$ to represent turkey sandwiches and $y$ to represent steak sandwiches.

$x$ = turkey sandwiches

$y$ = steak sandwiches

$x + y = 925$ total sandwiches that were sold

$4x + 6y = 4524$ dollars that were made

$x + y = 925\\y = 925 - x$

Now that we know what $y$ (steak sandwiches) equals, we plug it in to an equation to find $x$ .

$4x + 6(925-x) = 4524\\4x + 5550 -6x=4524\\$

Now, we subtract 5,550 from BOTH sides so we can get x by itself.

$-2x + 5550 - 5550 = 4524 - 5550\\-2x = -1026$

Next, we divide both sides by 2, so x is bare.

$\frac{2x}{2} = \frac{1026}{2}$

$x = 513$

Since x represents turkey sandwiches, we have our answer: 513 turkey sandwiches were sold.

I hope this helps! :)

Jenny multiplies the square root of her favorite positive integer by $\sqrt{2}$. Her product is an integer. a) Name three number

Dmitry [639]

Answer:

Part a) $2,50,18$

Part b) When Jenny divides the square root of her favorite positive integer by $\sqrt{2}$ , she gets an integer

Step-by-step explanation:

Let

x-------> the favorite positive integer

Part a)

1) For $x=2$

$\sqrt{2}*\sqrt{2}=\sqrt{4}=2$ -----> the product is an integer

The number $x=2$ could be Jenny favorite positive integer

2) For $x=50$

$\sqrt{50}*\sqrt{2}=\sqrt{100}=10$ -----> the product is an integer

The number $x=50$ could be Jenny favorite positive integer

3) For $x=18$

$\sqrt{18}*\sqrt{2}=\sqrt{36}=6$ -----> the product is an integer

The number $x=18$ could be Jenny favorite positive integer

Part B)

1) For $x=2$

$\sqrt{2}/\sqrt{2}=\sqrt{1}=1$ -----> the result is an integer

2) For $x=50$

$\sqrt{50}/\sqrt{2}=\sqrt{25}=5$ -----> the result is an integer

3) For $x=18$

$\sqrt{18}/\sqrt{2}=\sqrt{9}=3$ -----> the result is an integer

Therefore

When Jenny divides the square root of her favorite positive integer by $\sqrt{2}$ , she gets an integer

There isn't enough info to determine that, I believe. You would need an equation that would allow me to determine the minimum output for an A.
