Density =10 i.e. In every 1m^2 10 honey bees live !

<u>Step-by-step explanation:</u>

We have , A population of 6,000 honey(Correction as this isn't given in question ) bees lives in a rectangle-shaped area of the woods that is 30 meter long by 20 meters wide. We need to find What is the population density of the honey bees. Let's find out:

We know that ,

Population density = (Population) / (Land Area)

Now , Area of rectangle = length(width)

⇒ Area = Length(width)

⇒ Area = 30(20)

⇒ Area = 600m^2

Hence ,

⇒ Density = \frac{6,000}{600}

⇒ Density =10

Therefore , Density =10 i.e. In every 1m^2 10 honey bees live !

Solve the simultaneous equations<br>4x+3y=1<br>4x^2+3xy+y^2=2​
Fantom [35]

Notice that the second equation,

4<em>x</em> ² + 3<em>xy</em> + <em>y</em> ² = 2

can be written as

<em>x</em> (4<em>x</em> + 3<em>y</em>) + <em>y</em> ² = 2

and the first equation says 4<em>x</em> + 3<em>y</em> = 1, so this reduces to

<em>x</em> + <em>y</em> ² = 2

Solve the first equation for <em>x</em> :

4<em>x</em> + 3<em>y</em> = 1

4<em>x</em> = 1 - 3<em>y</em>

<em>x</em> = (1 - 3<em>y</em>)/4

Substitute this into the reduced second equation to get a quadratic equation in <em>y</em>, which happens to be easily factorized and solved:

(1 - 3<em>y</em>)/4 + <em>y</em> ² = 2

1 - 3<em>y</em> + 4<em>y</em> ² = 8

4<em>y</em> ² - 3<em>y</em> - 7 = 0

(4<em>y</em> - 7) (<em>y</em> + 1) = 0

4<em>y</em> - 7 = 0   <u>or</u>   <em>y</em> + 1 = 0

<em>y</em> = 7/4   <u>or</u>   <em>y</em> = -1

Solve for <em>x</em> :

<em>x</em> = (1 - 3 (7/4))/4   <u>or</u>   <em>x</em> = (1 - 3 (-1))/4

<em>x</em> = -17/16   <u>or</u>   <em>x</em> = 1

So the two solutions are (<em>x</em>, <em>y</em>) = (-17/16, 7/4) and (<em>x</em>, <em>y</em>) = (1, -1).

How do I solve 1/2 in minus 3 equals 5 ​
Mandarinka [93]

Answer:

  n = 16

Step-by-step explanation:

\dfrac{1}{2}n-3=5\\\\\dfrac{1}{2}n=8 \qquad\text{add 3}\\\\n=16 \qquad\text{multiply by 2}

___

In general, you identify the terms containing the variable. Then figure out what is being done to the variable. Here, it is multiplied by 1/2 and then 3 is subtracted. You undo these operations in reverse order.

Undo the subtraction of 3 by adding 3. Undo the multiplication by 1/2 by multiplying by its inverse, 2. Of course, the rules of equality tell you that anything you do to one side of the equation must also be done to the other side.

You can consider it as "unwrapping the package". You start at the outside, the last operation applied, and work your way in.
