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.

Find the equation of a line parallel to y'= -8x+6.

Verizon [17]

Answer:

The equation must include -8 as the slope

Step-by-step explanation:

Hi there!

Two key points to keep in mind:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0).
Parallel lines always have equal slopes

Given the equation y=-8x+6, we can identify that -8 is in the place of m in y=mx+b, making it the slope.

For a line to be parallel to y=-8x+6, it would have to have a slope of -8 as well. This is the only quality a line needs to be parallel to this given line.

I hope this helps!

Evaluate 2.6 raised to the seventh power divided by 2.6 raised to the sixth power, all raised to the second power.

igomit [66]

The evaluation of 2.6 raised to the seventh power divided by 2.6 raised to the sixth power, all raised to the second power is as follows:

$(\frac{2.6^{7} }{2.6^{6} } )^{2} = 6.76$

<h3>How to evaluate an expression?</h3>

2.6 raised to the seventh power divided by 2.6 raised to the sixth power, all raised to the second power.

The following expression can be evaluated as follows;

$(\frac{2.6^{7} }{2.6^{6} } )^{2}$

Using the law of indices,

$(A^{x} )^{y} = A^{xy}$

Therefore,

$(\frac{2.6^{7} }{2.6^{6} } )^{2} = (\frac{2.6^{14} }{2.6^{12} } )$

Using the law of indices,

$\frac{A^{x} }{B^{y} } = A^{x-y}$

Hence,

$(\frac{2.6^{7} }{2.6^{6} } )^{2} = (\frac{2.6^{14} }{2.6^{12} } ) = 2.6^{14-12} = 2.6^{2} = 6.76$

Therefore,

$(\frac{2.6^{7} }{2.6^{6} } )^{2} = 6.76$

The evaluation of 2.6 raised to the seventh power divided by 2.6 raised to the sixth power, all raised to the second power is 6.76.

If x + 4 = 32, does x = 8?

miss Akunina [59]

Answer:

Step-by-step explanation:

I say no because if we were to replace x with 8, the equation should look like this = 8 + 4 = 32. Since this doesn't make sense, 8 cannot be x. X would be 28 which would equal 32 and would be the right answer.
