You can put $n$ different elements in order in $n!$ different ways.

So, you can visit 12 different cities in $12!=479001600$ different ways.

Answer: 479,001,600

Step-by-step explanation:

There are 12 ways to go to the first place, 11 for the second, ten for the third, and so on. So 12! Means 12x11x10x9x8x7x6x5x4x3x2x1.

A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number less than 3

pav-90 [236]

1/3, because the probability in the cube is 1/6, and there are 2 numbers less than 3. So, 2/6 and simplify 2/6 to 1/3.

Larger number:<br> Smaller number:

3241004551 [841]

Let:

Larger number = x

Smaller number = y

-------------------------------------------------------------------------------------------------------------------

x + y = 49

x - y = 21

-------------------------------------------------------------------------------------------------------------------

Isolate the x in the first equation. Subtract y from both sides

x + y (-y) = 49 (-y)

x = 49 - y

-------------------------------------------------------------------------------------------------------------------

Now that we know what x is, plug in 49 - y (which = x) into x in the other equation.

x - y = 21

(49 - y) -y = 21

Simplify.

49 -2y = 21

Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract 49 from both sides

-2y +49 (-49) = 21 (-49)

-2y = 21 - 49

-2y = -28

Next, divide -2 from both sides to isolate the y

-2y/-2 = -28/-2

y = -28/-2

y = 14

-------------------------------------------------------------------------------------------------------------------

Now that we know what y is, plug into one of the equations.

x + y = 49

x + (14) = 49

Isolate the x. Subtract 14 from both sides

x + 14 (-14) = 49 (-14)

x = 49 (-14)

Simplify

x = 35

-------------------------------------------------------------------------------------------------------------------

Answer:

Larger number: 35

Smaller number: 14

-------------------------------------------------------------------------------------------------------------------
