2. A ski lodge offers two weekend packages. Package A provides 2 nights and 3 meals for $280. Package B provides 2 nights and 5

meals for $320. Write and solve a system of equations to find the costs per night and per meal. (Assume the cost per night and cost per meal are the same for both packages.) Use n to represent the cost per night and m to represent the cost of each meal. (8 points) Step 1: The equation representing package A is given. Complete the system of equations by writing an equation to represent package B. (1 point) Package A: 2n + 3m = 280 Package B: ___________________ Step 2: Select a method for solving the system. Which method did you choose? Why? (2 points) Step 3: Solve the system of equations to find the costs per night and per meal. Show your work.(3 points) Step 4: Explain the meaning of the solutions for m and n. (2 points: 1 point each)

Answer:

see below

Step-by-step explanation:

Package A

2n + 3m = 280

Package B

2n + 5m = 320

Using elimination to eliminate n since the coefficient is the same

Subtracting the A equation from the B equation

2n + 5m = 320

-2n - 3m = -280

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

    2m = 40

Divide by 2

2m/2 = 40/2

m = 20

Now finding n

2n+3m = 280

2n +3(20) = 280

2n+60 = 280

Subtract 60 from each side

2n +60-60= 280-60

2n = 220

Divide by 2

2n/2 = 220/2

n = 110

The cost per night is 110  and the cost per meal is 20

Let's go ahead and find the volume of a prism, then double the dimensions and see what happens to the volume. Then we can apply it to your volume.

volume of a prism with dimensions 2x2x2
v= 2x2x2 = 8 units^3

Now let's double it

volume of prism with dimensions 4x4x4
v= 4x4x4 = 64 units^3

So we see that by doubling the dimensions we multiply the volume by a factor of 8.  Let's do that for your volume, 3.5 m^3

3.5 x 8 = 28 m^3

Salsk061 [2.6K]

Answer:

1 meter =1,000 millimeters. So, the scale is:


7 mm:1,000 mm                      Divide both sides by 7


1 mm:142 6/7 mm - This is the scale that Tess used.

What is the probability of drawing a face card from a standard deck of cards and rolling a 3 or more on a 20-sided dice?
Nastasia [14]

Answer: 20.77%

Step-by-step explanation:

There are 52 cards in a standard deck. Out of these cards, there are 12 face cards. Thus, the probability of drawing a face is 12/52.

On a 20-sided dice, there are 20 options of numbers to roll. Out of these 20 numbers, 18 of the numbers are greater than or equal to 3, making the probability 18/20, or 9/10.

To find the probability of two events, you need to multiply the probabilities together. Thus, you need to multiply 12/52 by 9/10.

(12/52) * (9/10) = 27/130

27/130 is about equal to 0.2077, or a 20.77% probability.
