Although part of your question is missing, you might be referring to the question :

Given that 2x+3y / 3x+4y = 5, find the ratio of y:x

Given : 2x+3y / 3x+4y =5

To find : y : x

Solution :

(2x+3y) / (3x+4y) = 5, or

2x + 3y = 15x + 20y, or

-15x + 2x = 20y - 3y, or

-13x = 17y

Therefore, x/y = -17/13

Hence, y/x = -13/17

y : x = -13 : 17.

The answer is -13 : 17.

2 dilated means that the measurement of an area has increased or expanded in size.

This can be a linear measurement such as the diameter of a circle, or the area of a square or rectangle. The formula for the area of a circle is A=πr2 where r is the radius of the circle. A 2 dilated measurement would mean that the radius has doubled, so the formula would be A=π(2r)2 A=4πr2. This would mean that the area of the circle has increased by a factor of 4. Similarly, if the length and width of a rectangle were 2 dilated, the area would be A=2L2W, which would be four times the original area.

Answer:

There are 14 pizza rolls and 2 mini hot dogs in the combination meal.

Step-by-step explanation:

From the question, we have the following parameters

Pizza roll = 55 calories each

Mini hotdog = 70 calories each

Combination meal = 910 calories in total

Let the pizza roll be x and the mini hotdog be y

So, we have

55x + 70y = 910

x = 12 + y

Make x the subject in x = 12 + y

x = 12 + y

Substitute x = 12 + y in 55x + 70y = 910

55(12 + y) + 70y = 910

Evaluate

660 + 55y + 70y = 910

So, we have

125y = 250

This gives

y = 2

Recall that

x = 12 + y

So, we have

x = 12 + 2

x = 14

Hence, there are 14 pizza rolls and 2 mini hot dogs

Speed = 7.7miles/2.2hours = 3.5miles/hour

In physics, the average speed is defined as the ratio of distance traveled during a certain time period.

Distance/Time = Speed

If the problem stated that the two groups’ average speeds are equal,

Mark’s Group Speed Equals Sally’s Group Speed

The problem now suggests that the time is likewise equal. That means Sally’s group took t = 4.7 – 2.5 = 2.2 hours to travel the remaining 7.7 miles.

That implies that the speed is,

7.7 miles/2.2 hours = 3.5 miles/hour.

Answer:

the equation of the line = y + x -3 -3 = 0

Step-by-step explanation:

Equation of the line is give n by the formula

y - y¹ = m

x - x¹

note: m is the gradient.

Point = (3, 3) and (-1, 7).

Gradient =m= y2 - y1 = 7 - 3 = 4 = -1

x2 - x1 -1 -3 -4

the equation of the line

y - y1 = m

x - x1

y - 3 = -1

x - 3

note: Perform cross multiplication also remember every whole number is over one.

=y - 3 = -1 (x - 3)

=y - 3 = - x + 3

y + x - 3 - 3 = 0.

A line can be represented in the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

Given that m = −72 and the y-intercept is 12, we can represent the line as y = −72x + 12

We are also given that the point (x, 5) lies on the line. So we can substitute the x and y values of the point into the equation of the line to find the value of x.

y = −72x + 12

5 = −72x + 12

-7 = -72x

x = 7/72

So the value of x is 7/72.

We can also get this by solving the equation of the line for x.

y = -72x + 12

y - 12 = -72x

(y - 12)/-72 = x

x = (y - 12)/-72

So for any point (x, y) on the line, the value of x can be obtained by substituting y and the slope-intercept form equation.

Answer: To get another turn, Sydney's score must be greater than 1. Therefore, to find the lowest number that Sydney can roll to get another turn, we need to find the smallest number that, when multiplied by the fraction on the card, will give a result greater than 1.

It's not mentioned which fraction card Sydney drew, so we can assume any fraction.

Let's assume the fraction card is labeled 1/4.

To get another turn, Sydney's score must be greater than 1. Therefore, we need to find the smallest number that, when multiplied by 1/4, will give a result greater than 1.

1/4 * x >1

x > 4

The proof is given below

We can start by using the definition of the trigonometric functions cosec(A), tan(A), and cot(A):

cosec(A) = 1/sin(A)

tan(A) = sin(A)/cos(A)

cot(A) = 1/tan(A) = cos(A)/sin(A)

Now, we can substitute these definitions into the equation:

cosec(A)/(tan(A) + cot(A)) = 1/sin(A) / (sin(A)/cos(A) + cos(A)/sin(A))

Simplifying the right-hand side gives us:

1/sin(A) / (sin(A)(1/cos(A) + 1/sin(A))) =

1/sin(A) / (sin(A)/sin(A)cos(A) + sin(A)) =

1/sin(A) / (1 + sin(A))

Finally,

multiplying both sides by sin(A) (which is not 0 because A is not a multiple of pi/2)

cosec(A)/(tan(A) + cot(A)) * sin(A) = 1/sin(A) / (1 + sin(A)) * sin(A) = 1 / (1 + sin(A)) * sin^2(A) = cos(A)

Therefore, cosec(A)/(tan(A) + cot(A)) = cos(A)
