Separate the two equations and set them equal to 0. It would look like this:
x+3=0
-2x+5=0

IRINA_888 [86]

Ok if half are female that means 40 than 80 more for each of them because they all produce 80 so 80 times 40 = 3200 your gonna do the same 2 more times because of 3 generations so 3200 times 3 = 9600 in total

BD is the angle bisector of

AlexFokin [52]

Note: Let us consider, we need to find the $m\angle ABC$ and $m\angle DBC$ .

Given:

In the given figure, BD is the angle bisector of ABC.

To find:

The $m\angle ABC$ and $m\angle DBC$ .

Solution:

BD is the angle bisector of ABC. So,

$m\angle ABD=m\angle DBC$

$3x=x+20$

$3x-x=20$

$2x=20$

Divide both sides by 2.

$x=\dfrac{20}{2}$

$x=10$

Now,

$m\angle DBC=(x+20)^\circ$

$m\angle DBC=(10+20)^\circ$

$m\angle DBC=30^\circ$

And,

$m\angle ABC=(3x)^\circ+(x+20)^\circ$

$m\angle ABC=(4x+20)^\circ$

$m\angle ABC=(4(10)+20)^\circ$

$m\angle ABC=(40+20)^\circ$

$m\angle ABC=60^\circ$

Therefore, $m\angle DBC=30^\circ,m\angle ABD=30^\circ$ and $m\angle ABC=60^\circ$ .

5b^2-5b-8b+4+24b^2-1-13b^2-b

nexus9112 [7]

Answer:

The answer would be 16b^2 - 14b + 3

Step-by-step explanation:

In order to find this, we simply need to group the terms by their variable values. We will start with the b^2 terms.

5b^2 + 24b^2 - 13b^2 = 16b^2

Now we can use all of the b terms.

-5b - 8b - b = -14b

And finally, we'll do all the constants.

4 - 1 = 3

Using all three of these together will give us the simplified form.

Elenna [48]

Answer:

x = 8

Step-by-step explanation:

The line segment inside the triangle is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

$\frac{11x-4}{9x}$ = $\frac{7x}{6x}$ ( cross- multiply )

6x(11x - 4) = 63x² ← distribute left side

66x² - 24x = 63x² ( subtract 63x² from both sides )

3x² - 24x = 0 ← factor out 3x from each term on the left side

3x(x - 8) = 0

Equate each factor to zero and solve for x

3x = 0 ⇒ x = 0

x - 8 = 0 ⇒ x = 8

But x > 0 , then x = 8
