4> 1/2+ 2

4 > 1/2 + 4/2

4> 5/2

8/2> 5/2 ---> I verifies!!!

(-1, 1)

1 > (1/2)(-1) + 2

1> -1/2 + 2

1 > -1/2 + 4/2

1 > 3/2 ---> Not verify!!

(2, 3):

2 > (1/2)*2 + 2

2 > 1 + 2

2 > 3 ---> Not verify!!!

(0, 2)

2 > (1/2)*0 + 2

2 > 2 ---> Not verify!!!

So, the only pair that verifies is (1, 4)

Answer:

4, 16 and 10

Step-by-step explanation:

Here we would like to work with a system of 3 equations, we need ti find them. Lets call s the 10oz coffees, m the 14oz and l the 20oz.

As Kyle sold $37.2 selling 3 different types of coffee at their respective prices we can say:

revenue = s*0.95 + m*1.15 + l*1.5 = 37.2 [equation 1]

And as he sold 30 cups:

s + m + l = 30 [equation 2]

And as the total volume of coffee is 464 oz:

s*10 + m*14 + l*20 = 464 [equation 3]

So, we have a system of 3 equations with three unknowns s, m and l.

Take the eq 2 and subtract m and l in both sides:

s = 30 - m - l

Now, take it and replace in the other 2:

(30 - m - l)*10 + 14m + 20l = 464 [eq 3]

0.95(30 - m - l) + 1.15m + 1.5l = 37.2 [eq 1]

Working with equation 3:

300 -10m -10l + 14m + 20l = 464

300 + 4m + 10l = 464

4m + 10l = 164 [equation 3']

Now with eq 1:

0.95(30 - m - l) + 1.15m + 1.5l = 37.2

28.5 - 0.95m - 0.95l + 1.15m + 1.5 l = 37.2

28.5 + 0.2m + 0.55l = 37.2

0.2m + 0.55l = 8.7 [equaiton 1']

Now we passed to a 2-equation system with eq 1' and eq 3'.

Take eq 3' and subtract 4m in both sides:

10l = 164 - 4m

Now divide by 10 in both sides

l = [164 - 4m]/10

Now, with this value for l replace in eq 1':

0.2m + 0.55 ( [164 - 4m]/10) = 8.7

0.2m + 0.055 (164 - 4m) = 8.7

0.2m + 9.02 - 0.22m = 8.7

- 0.02m = -0.32

m = -0.32/-0.02

m = 16 ----> 16 14oz coffees

Now replace m=16 in eq 1' or 3' to find l:

4m +10l = 164

64 + 10l = 164

10l = 100

l = 10 ----> 10 20oz coffees

So, finally we replace l=10 and m=16 in equaiton 2:

s + m + l = 30

s + 16 +10 = 30

s = 30 - 26

s = 4

So, Kyle filled 4 10oz coffes, 16 14oz coffees and 10 20oz coffees.

Answer:

40,000 ft

Step-by-step explanation:

The area of a rectangle is weight*length, and the perimeter is the sum og the four sides, which are 2 lengths sides ans 2 width sides, so:

area = w*l

perimeter = 2w + 2l

If the perimeter is 1000 ft:

2w + 2l = 1000

Also, the length is 300 ft more than width, so:

l = 300 +w

So, our system is:

2w + 2l = 1000 (equation 1)

l =300 + w (equation 2)

Son, we can solve it by replacing equation 2 in equation 1:

2w + 2(300 +w) = 2w + 600 + 2w = 4w + 600 = 1000

Now, subtract 600 in both sides:

4w + 600 - 600 = 1000 - 600

4w = 400

Divide both sides by 4:

4w/4 = 400/4

w = 100

Lets replace this w value in equation 2 to find l:

l = 300 + 100 = 400, so l=400

Finally we can find the area using the area formula:

area = 400*100 = 40,000 ft2

So, the area is 40,000 ft2

Final answer:

The area of the pasture is found by setting up and solving a linear system (1000 = 2w + 2(w + 300)); the dimensions of the rectangle are found to be 100 feet in width and 400 feet in length. The area is then calculated by multiplying the width by the length, yielding an area of 40,000 square feet.

Explanation:

To solve the problem, we need to establish a system of linear equations to find the dimensions of the pasture. Given that the perimeter of a rectangle is 2 times the width plus 2 times the length (P = 2w + 2l), and the length is 300 feet more than its width (l = w + 300), we can set up the following equations:

P = 2w + 2l

l = w + 300

Since we know the perimeter is 1000 feet, we substitute this value into the first equation:

1000 = 2w + 2(w + 300)

1000 = 2w + 2w + 600

1000 = 4w + 600

400 = 4w

w = 100 feet

Once we have the width, we can substitute this into the second equation to find the length (l):

l = 100 + 300

l = 400 feet

To find the area of the pasture, we multiply the width by the length:

Area = width × length = 100 feet × 400 feet = 40,000 square feet

The area of the pasture is 40,000 square feet.

Answer:

The runner's unit rate is 0.09 miles/minute.

Step-by-step explanation:

Given:

Distance cover by runner = 8 miles and the time taken = 92 minutes.

Now, to calculate the runner's unit rate.

We put the formula to get the unit rate:

Velocity = distance/time

[tex]v=\frac{d}{t}[/tex]

[tex]v=\frac{8}{92}[/tex]

[tex]v=0.0869[/tex]

v = 0.09 miles/minute (approximately)

Therefore, the runner's unit rate is 0.09 miles/minute.

Final answer:

To find the runner's unit rate, divide the total miles (8) by the total minutes (92), resulting in a rate of 0.08695652 miles per minute or 5.217 miles per hour when converted.

Explanation:

The question is asking to find the unit rate of a runner who runs 8 miles in 92 minutes. To find the unit rate, we need to calculate how many miles the runner can run in one minute. This involves dividing the total miles run by the total minutes taken.

Calculation:
Unit Rate = Total Miles / Total Minutes = 8 miles / 92 minutes = 0.08695652 miles per minute.

For practical purposes and better understanding, it might be useful to convert this unit rate into miles per hour. Since there are 60 minutes in an hour, we simply multiply the unit rate per minute by 60.

Miles per hour = 0.08695652 miles/minute * 60 minutes/hour = 5.217 miles per hour.

Therefore, the runner's unit rate is 0.08695652 miles per minute, or equivalently, 5.217 miles per hour.

A dependent clause is a group of words that contains a subject and verb but does not express a complete thought. A dependent clause cannot be a sentence. Often a dependent clause is marked by a dependent marker word.  A dependent marker word is a word added to the beginning of an independent clause that makes it into a dependent clause. Some common dependent markers are: after, although, as, as if, because, before, even if, even though, if, in order to, since, though, unless, until, whatever, when, whenever, whether, and while.

Answer:

Elliot will make 4 hats and 16 scarves

Step-by-step explanation:

Let x be the number of hats and y be the number of scarves Elliot will make.

Elliott wants to make a total of 20 items, then

x + y = 20

Each hat uses 0.2 kilograms of yarn, so x hats use 0.2x kilograms of yarn and each scarf uses 0.1 kilogram of yarn, then y scarves use 0.1y kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats, then

0.1y = 2(0.2x)

Thus,

0.1y = 0.4x

y = 4x

Substitute it into the first equation:

x + 4x = 20

5x = 20

x = 4

y = 20 - 4

y = 16

Hence, Elliot will make 4 hats and 16 scarves

The left side of the original equation becomes 2x+3. The right side is also 2x+3. Both sides are the same, so we get infinitely many solutions.

We have,

[tex]6(\frac{1}{3}x+\frac{1}{2})=2x+3[/tex]

First distribute 6 through parentheses

[tex]2x+3=2x+3[/tex]

We can see both sides are equal hence for all x the equation will result with tautology (undeniable equality).

The answer is [tex]x \in \mathbb{R}[/tex].
