Two numbers x and y, have a sum of 23 and a difference of 7. x is greater than y
Verizon [17]

Answer:

Below in bold.

Step-by-step explanation:

Use the elimination method:

a.   x + y = 23

     x - y = 7

b.  Adding the 2 equations eliminates y, so we have

     2x = 30

        x = 15.

     Substitute x = 15 in equation a:

      15 + y = 23

         y = 23 - 15

        y =  8.

       Answer x = 15, y = 6.

Birds burgers barn sold 485 hamburgers today. The number sold with cheese wise half the number sold without cheese. How many of
frez [133]

Answer:

The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330

Step-by-step explanation:

<u><em>The correct question is</em></u>

Birds burgers barn sold <em>495 hamburgers</em> today. The number sold with cheese wise half the number sold without cheese. How many of each kind were sold?

Let

x -----> the number of hamburgers sold with cheese

y -----> the number of hamburgers sold without cheese

we know that

x+y=495 -----> equation A

x=\frac{1}{2}y ----> equation B

substitute the equation B in equation A and solve for y

y+\frac{1}{2}y=495

\frac{3}{2}y=495

y=495(2)/3

y=330

Find the value of x

x=\frac{1}{2}330=165

therefore

The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330

Anyone know this one?
Dvinal [7]

Answer:

3

Step-by-step explanation:

<em>This is cube root (hence the </em>\sqrt[3]{}).

To find the cube root of a number, we are looking for a number that, when multiplied by itself 3 times, equals the number inside the sign.

So:

3^x = 27

We know that 2\cdot 2\cdot 2 = 8, so this doesn't work.

We also know that 3 \cdot 3 \cdot 3 = 27, so this works.

Therefore the cube root of 27 is 3.

Hope this helped!
