Brian drinks tea at an incredable rate he drinks 3 1/2 liters of tea every 2/3 of an hour . Ben drinks at a constant rate how many liters of tea does he drink in one hour

Answers

Answer:

5 1/2 liters of tea

Step-by-step explanation:

Brian drinks tea at an incredable rate he drinks 3 1/2 liters of tea every 2/3 of an hour . Ben drinks at a constant rate how many liters of tea does he drink in one hour

3 1/2 =>7/2 => 2/3 hour

Hence:

2/3 hour = 7/2 liters

1 hour = x

Cross Multiply

2/3 x = 1 × 7/2

x = 7/2 ÷ 2/3

x = 7/2 × 3/2

x = 21/4

x = 5 1/4 liters

Hence, Brian drinks 5 1/4 liters in 1 hour

Step-by-step explanation:

Remember that it doesn't matter how many numbers are after the tenths place of a decimal point what matters is the tenths place itself. If you have a decimal that has dozens of numbers but it's tenth place is a 3 and then you have a decimal with 5 numbers in whole but it's tenths place is 4, the 4 is greater then the 3 simply because it's greater in tenths.

Write an equation of the line that passes through a pair of points:
(-5,-2), (4,5)
It’s not b

Answers

Answer:

C

Step-by-step explanation:

We want to determine the equation of the line that passes through the points (-5, -2) and (4, 5).

First, let’s determine the slope of the line. We can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (-5, -2) be (x₁, y₁) and let (4, 5) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{5-(-2)}{4-(-5)}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{5+2}{4+5}=\frac{7}{9}[/tex]

So, our slope is 7/9.

Now, we can use the point-slope form to determine the rest of the equation:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, we will substitute 7/9 for m.

For consistency, we will also let (x₁, y₁) be (-5, -2). Hence:

[tex]\displaystyle y-(-2)=\frac{7}{9}(x-(-5))[/tex]

Simplify:

[tex]\displaystyle y+2=\frac{7}{9}(x+5})[/tex]

Distribute:

[tex]\displaystyle y+2=\frac{7}{9}x+\frac{35}{9}[/tex]

Subtract 2 from both sides. Note that 2 is equivalent to 18/9. Hence:

[tex]\displaystyle y=\frac{7}{9}x+\frac{35}{9}-\frac{18}{9}[/tex]

Simplify:

[tex]\displaystyle y=\frac{7}{9}x+\frac{17}{9}[/tex]

Therefore, our answer is C.

Answers

Answer: its b

Step-by-step explanation:

The system of equations x - 3y = 6; 5x - y = 10 is represented by lines m and n respectively. which is the correct option (C).

What is the slope of the line?

The slope of a line is defined as the gradient of the line.

Given that line M passes through the points (-3, -3) and (6, 0).

Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

x₁ = -3, y₁ = -3

x₂ = 6, y₂ = 0

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Substitute values in the equation, we get

⇒ y - (-3) = (0 - (-3))/(6-(-3) )[x -(-3))

⇒ y + 3 = 3/9(x + 3)

⇒ y + 3 = 1/3(x + 3)

⇒ 3y + 9 = (x + 3)

⇒ x - 3y = 6

Given that line N passes through the points (-3, -25) and (6, 20).

⇒ y - (-25) = (20 - (-25))/(6-(-3) )[x -(-3))

⇒ y + 25 = 45/9(x + 3)

⇒ y + 25 = 5(x + 3)

⇒ y + 25 = 5x + 15

⇒ 5x - y = 10

Therefore, the system of equations x - 3y = 6; 5x - y = 10 is represented by lines m and n respectively.

What is the difference of the values of the two variables in this system of equations?
y= 2x + 1
x + 3y = 10

Α. 0

B. 1

C. 2

D. 3

Answers

a is your answer to this

Answer: C

Step-by-step explanation: y = 2x + 1, x + 3y = 10 in these two equations you can put y = 2x + 1 in 3y in x + 3y = 10 so it would be x + 3(2x + 1) = 10,

x + 6x + 3 = 10, 7x = 7 so x = 1 and when we put the value of x in y = 2x + 1, it would be y = 2(1) + 1 so y = 3. difference would be 3 - 1 = 2 so it is C

A tour company for large groups charges a one time fee of $200 plus an additional $25 per person who goes on the tour. They must make at least $1,650 to make the tour profitable. Let n be the number of people going on the tour. Write and solve an inequality in terms of n that represents all numbers of people who can go on the tour to make it profitable.

Answers

Answer:

200+25n=1650

n=58

Step-by-step explanation:

200+25n=1650

25n=1450

n=58

The solution of an inequality in terms of n that represents all numbers of people who can go on the tour to make it profitable would be 58.

What is a solution set to an inequality or an equation?

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Given that company for large groups charges a one time fee of $200 plus an additional $25 per person who goes on the tour.

Let's consider n be the number of people going on the tour.

Then the inequality in terms of n that represents all numbers of people who can go on the tour to make it profitable would be;

200+25n ≥1650

To solve for n;

200+25n=1650

25n=1450

n=58

Hence, the solution of an inequality in terms of n that represents all numbers of people who can go on the tour to make it profitable would be 58.
