\text {Number of ways} = \dfrac{17 \times 16 \times 15 \times 14 \times 13 \times 12}{1 \times 2 \times 3 \times 4 \times 5 \times 6}

\text {Number of ways} = \dfrac{8910720}{720}

\text {Number of ways} = 12376

Answer:

(-7, -8)

Step-by-step explanation:

To start we have to isolate a variable to get an equation for it.

Let's get an equation for x from the first equation:

x - 2y = 9

x = 2y + 9

Now that we know what x is in terms of y, lets plug it into our second equation:

3(2y + 9) - 5y = 19

6y + 27 - 5y = 19

y + 27 = 19

y = -8

Now that we know what y equals, let's plug it into our first equation and solve for x:

x - 2(-8) = 9

x + 16 = 9

x = -7

Now that we have x and y, we make our ordered pair, in terms of (x, y):

(-7, -8)

Hope this helps!

Find the area of a circle with a circumference of 6.28 unitesz
Anni [7]

Answer:

3.14 square units

Step-by-step explanation:

Circumference of a circle = 2πr

2πr = 6.28

r = 6.28/2π

r = 3.142/π

Area of a circle = πr^2

slot in the value of r

Area of the circle = π( 3.142/π)^2

               "              = π(9.87/ π^2)

                "             = 9.87/π

π = 3.14

Area of a circle = 9.867/ (3.14)

              "            = 3.14 square units

What should we subtract from 50/29 to get 24
Scrat [10]

Answer:

-22.28

Step-by-step explanation:

Let the number to be subtracted from 50/29 to get 24 to be x

So this can be written as : 50/29 - x =24 ----collect like terms as

50/29 - 24 = x

1.72 -24 = x

-22.28 = x

So to check the answer;

50/29 -{x} = 24

50/29 - {- 22.28} = 24

1.72+ 22.28 = 24 ---correct.
