There are 12 cookies in a container. There are 12 containers packed in a box for shipping. There are 12 boxes loaded onto a ship

mamaluj [8]

Option A

Total number of cookies on a shipping truck when 12 boxes are loaded is 1728.

<u>Solution:</u>

Need to determine correct option of total number of cookies on the truck

From given information

Number of cookies in 1 container = 12

Number of container in 1 box = 12

So number of cookies in 1 box = number of cookies in 12 container

$\Rightarrow \text { Number of cookies in } 1 \text { box }=\text { number of cookies in } 1 \text { container } \times 12$

$=12 \times 12=144$

Number of boxes loaded onto 1 shipping truck = 12

So Number of cookies onto 1 shipping truck = number of cookies in 12 boxes

$\Rightarrow \text { Number of cookies onto } 1 \text { shipping truck }=\text { number of cookies in } 1 \text { box } \times 12$

$=144 \times 12=1728$

Hence total number of cookies on a shipping truch when 12 boxes are loaded is 1728. Thus option A is correct

You would divide 27/6.75.

You'd get 4, so 4 people went.

To check you would do 4x6.75 and your get the total of 27$

Alexxx [7]

Answer:

x = 2 | y = 3. ( 2,3 )

Step-by-step explanation:

2(3x + 3y = 15)

6x + 6y = 30

3(4x + 2y = 14)

12x + 6y = 42

- 6x. -6y. -30

6x = 12

÷ 6. ÷6

x = 2

3x + 3y = 15

3(2) + 3y = 15

6 + 3y = 15

-6. -6

3y = 9

÷3. ÷3

y = 3
