Answer:

M = 1.75 --- Movies

V = 5.5 --- Video games

Step-by-step explanation:

Represent the movies with M and the video games with V.

The first month, the expression is:

2M + 3V = 20

The next month, the expression is:

6M + 5V = 38

Required

Find M and V

We have:

2M + 3V = 20 --- (1)

6M + 5V = 38 --- (2)

Multiply (1) by 3.

3 * 2M + 3V = 20

6M + 9V = 60 --- (3)

Subtract (1) from (3)

6M + 9V = 60

- 6M + 5V = 38

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

6M - 6M + 9V - 5V = 60 -38

4V = 22

Divide by 4

V = 5.5

Substitute 5.5 for V in (1)

2M + 3V = 20

2M  + 3 * 5,5 = 20

2M  + 16.5= 20

Subtract 16.5 from both sides

2M = 3.5

Divide by 2

M = 1.75

Carol used 114 cups of flour in 2 muffins. How many cups of flour are needed to make 12 similar muffins?
son4ous [18]

Answer:

7 1/2 cups

Step-by-step explanation:

If Carol uses 1 1/4 cups of flour for 2 muffins, then she will need to repeat this conversion 6 times since she wants to make identical 12 muffins in all.

So, 1 1/4 * 6 = 7 1/2

Therefore, she needs 7 1/2 cups of flour

Hope that helps! :)

⦁ The population of the Tallahassee metropolitan area was 382,627 at the end of 2017 with a growth rate of 2.78%. Using the expo
a_sh-v [17]

Answer:

The exponential growth model for the population of the Tallahassee metropolitan area is y=382627(1.0278)^t.

Step-by-step explanation:

The exponential formula is

y=b(1+r)^t

Where b is initial population, r is growth rate, (1+r) is growth factor and t is time (in years) after the initial year.

The population of the Tallahassee metropolitan area was 382,627 at the end of 2017. The growth rate is 2.78%.

Here the initial year is 2017 and rate is 0.0278

y=382627(1+0.0278)^t

y=382627(1.0278)^t

Graph of the equation is shown below. The x-axis represents the number of years after 2017 and y-axis represents the total population.

Difference between 2025 and 2017 is 8 years. Put t=8

y=382627(1.0278)^8

y=382627(1.0278)^8

y=476479.828188\approx 476479

Therefore the projected population in 2025 is 476479.
