Answer:

Words for dividing:

  • shared
  • each
  • for every
  • per

The problem is asking you to divide, because the key word is, "fill empty egg cartons that each hold"

So Mary will fill  each carton with 12 eggs each until she runs out.

216 / 12

<em>12 goes into 216 eighteen times exactly.</em>

<em />12 * 18 = 216

<em>and the result is(R means leftovers, which are none here)...</em>

<em />18~R~0

A. Your bed is a rectangle that is 4 feet by 6 feet wide. Draw a model of it below and label the dimensions. Find the perimeter
musickatia [10]

The model which model the dimensions of the bed has been attached.

  • The perimeter and area of the bed is 10 feet and 24 square feet respectively.
  • The perimeter of your bed is less than the perimeter of the items, so not all items can be underneath your bed.

<h3>What is the perimeter and area of the bed?</h3>

  • Length of the rectangle = 6 feet
  • Width of the rectangle = 4 feet

Perimeter of the bed = 2(length + width)

= 2(6 + 4)

= 2(10)

= 20 feet

Area of the bed = Length × width

= 6 feet × 4 feet

= 24 square feet

  • Perimeter of the suitcase = 14 feet
  • Perimeter of Lego box = 10 feet
  • Perimeter of memory box = 10 feet
  • Perimeter of stash = 6 feet

Total perimeter = 14 + 10 + 10 + 6

= 40 feet

Therefore, the items listed can not all be underneath your bed because the total perimeter of the items is greater than the perimeter of your bed.

Using elimination method
bogdanovich [222]

Answer:

The value of x is 2 and y is (-5)

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • -7x + y = – 19
  • -2x + 3y = – 19
<h3><u>To </u><u>Find</u>;</h3>
  • The value of x and y
<h3><u>B</u>y<u> </u><u>Usin</u>g<u> </u><u>Elimination</u><u> </u><u>Method</u>;</h3>

First name the equation

  • -7x + y = – 19 ...(1)
  • -2x + 3y = – 19 ...(2)

Now, Multiply equation (1) by 3 we get,

3 × (-7x + y = – 19)

-21x + 3y = – 57

Now, Eliminate

-21x + 3y = – 57

-2x + 3y = – 19

<u>+</u><u> </u><u> </u><u> </u><u> </u><u>–</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>+</u><u> </u><u> </u><u> </u><u> </u>

-19x = -38

x = -38/-19

x = 2

Now, Put the value of x in equation (2) we get the value of y.

-7x + y = – 19

-7(2) + y = – 19

-14 + y = -19

-14 + 14 + y = -19 + 14

y = -5

Thus, The value of x is (-5) and the value of y is 2.

<h3><u>For </u><u>Verification</u>;</h3>

-7x + y = – 19

-7(2) + (-5) = – 19

-14 – 5 = – 19

-19 = -19

-2x + 3y = – 19

-2(2) + 3(-5) = – 19

-4 – 15 = – 19

-19 = -19

Here, L.H.S = R.H.S

Hence Verified!

Tyler has at most $20 to spend on rides and games at the carnival. Each ride costs $0.75 and each game costs $0.50. Which inequa
GaryK [48]

Answer:

The inequality that can be used to determine how many rides r and games g Tyler can pay for at the carnival is:

0.75r+0.50g≤20, where:

r is the number of rides

g is the number of games

Step-by-step explanation:

With the information provided, you can say that the amount spent at the carnival is equal to the cost per ride for the number of rides plus the cost per game for the number of games. Also, given that the statement indicates that Tyler has at most $20, the inequality would indicate that the amount spent has to be less than or equal to 20. According to this, the inequality that can be used to determine how many rides r and games g Tyler can pay for at the carnival is:

0.75r+0.50g≤20, where:

r is the number of rides

g is the number of games
