A farmer had twice as many chickens as ducks on his farm. After he sold 166 chickens and ducks, he had half as many chickens as

mamaluj [8]

Answer:

The farmer have at first 202 chickens.

Step-by-step explanation:

Given:

A farmer had twice as many chickens as ducks on his farm. After he sold 166 chickens and ducks, he had half as many chickens as ducks left.

Now, to find the chickens farmer have at first.

Let the chickens be $x.$

And, the ducks be $y.$

As, the farmer had twice as many chickens as ducks on his farm.

So, $x=2y$ ......(1)

As, given the farmer after selling 166 chickens and ducks, he had half as many chickens as ducks left.

According to question:

$x-166=(y-29)\times \frac{1}{2}$

$x-166=\frac{y-29}{2}$

Substituting the value of $x$ from equation (1) we get:

$2y-166=\frac{y-29}{2}$

By cross multiplying we get:

$4y-332=y-29$

Adding both sides 332 we get:

$4y=y+303$

Subtracting both sides by $y$ we get:

$3y=303$

Dividing both sides by 3 we get:

$y=101.$

Now, to get the number of chickens substituting the value of $y$ in equation (1):

$x=2y\\\\x=2\times 101\\\\x=202.$

Therefore, the farmer have at first 202 chickens.

You can find the rise by _ the Y-coordinate of the left point from the y-coordinate of the right point

bixtya [17]

Answer:

Subtracting

Step-by-step explanation:

We know that the slope of a line is given by the rise over run. where rise is vertical difference between two points and run is the horizontal distance between the points.

$\text{if }(x_1,y_1) \text{ and }(x_2,y_2)\text{ are two points on a line, then the}\\\text{slope of the line is given by}\\\\\text{Slope, }m=\frac{y_2-y_1}{x_2-x_1}\\\\\text{since slope}=\frac{\text{Rise}}{\text{Run}}, \text{ so Rise}=y_2-y_1\\\\\text{so we can find the rise by subtracting the Y-coordinate of the left point }\\\text{from the y-coordinate of the right point}.$
