Answer: The required expression is,

\frac{4\times 4\times 4\times 3}{16}

Step-by-step explanation:

Given,

The number of boxes Ray has = 3,

The number of layers of chocolate each box has = 4,

⇒ The total number of layers of chocolates = 4 × 3,

Now, Each layers has 4 rows of chocolate,

⇒ The total number of rows of chocolate = 4 × 4 × 3,

Also, Each row has 4 chocolates,

So, the total number of chocolates = 4 × 4 × 4 × 3,

He distributes these chocolates to his 16 friends,

Hence,

\text{Total number of chocolate got by each friend}=\frac{\text{Total chocolates}}{\text{Total friends}}

=\frac{4\times 4\times 4\times 3}{16}

Which is the required expression.

Answer:

Step-by-step explanation:

x - y = 34

x + y = 212

-------------------add

2x = 246

x = 246/2

x = 123 <=== 123 domestic

x + y = 212

123 + y = 212

y = 212 - 123

y = 89 <===== 89 foreign

A restaurant offers three sizes of coffee and four differerſt types of coffee.
Kruka [31]
<h3>Answer:  864</h3>

=======================================================

Work Shown:

There are,

  • 3 sizes of coffee
  • 4 types of coffee
  • 2 choices for cream (you pick it or you leave it out)
  • 2 choices for sugar (same idea as the cream)

This means there are 3*4*2*2 = 12*4 = 48 different coffees. We'll use this value later, so let A = 48.

There are 6 bagel options. Also, there are 3 choices in terms of if you order the bagel plain, with butter, or with cream cheese. This leads to 6*3 = 18 different ways to order a bagel. Let B = 18.

Multiply the values of A and B to get the final answer

A*B = 48*18 = 864

There are 864 ways to order a coffee and bagel at this restaurant.

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

If you're curious why you multiply the values out, consider this smaller example.

Let's say you had 3 choices of coffee and 2 choices for a bagel. Form a table with 3 rows and 2 columns. Place the different coffee choices along the left to form each row. Along the top, we'll have the two different bagel choices (one for each column).

This 3 by 2 table leads to 3*2 = 6 individual table cells inside. Each cell in the table represents a coffee+bagel combo. This idea is applied to the section above, but we have a lot more options.

How to factor x^2-2x-15
olga2289 [7]

Answer:

(x - 5)(x + 3)

Step-by-step explanation:

Given

x² - 2x - 15

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (- 2)

The factors are - 5 and + 3, since

- 5 × 3 = - 15 and - 5 + 3 = - 2, thus

(x - 5)(x + 3) ← in factored form
