17x/2 = 5

17x = 10

x = 10/17

so, you multiply 8 1/2 by 10/17, and you'll get 5

Answer:

<ADC=131°

Step-by-step explanation:

<ADC= <ADB+<BDC

We need to substitute the angle measures and simplify to get:

<ADC=89+42

This simplifies to give us:

$m \angle \: ADC = 131 \degree$

The correct answer from the given options is the first choice.

What is CD? Show steps please!

Romashka [77]

Answer:

$\large\boxed{CD=2\sqrt6\ cm}$

Step-by-step explanation:

ΔDAC and ΔDCB are similar (AA). Therefore the sides are in proportion:

$\dfrac{CD}{DA}=\dfrac{DB}{CD}$

We have DA = 3cm and DB = 8 cm. Substitute:

$\dfrac{CD}{3}=\dfrac{8}{CD}$ cross multiply

$CD^2=(3)(8)$

$CD^2=24\to CD=\sqrt{24}$

$CD=\sqrt{4\cdot6}\\\\CD=\sqrt4\cdot\sqrt6\\\\CD=2\sqrt6\ cm$

The formula to find a certain number in an arithmetic sequence is an=a1+d(n−1)an=a1+d(n−1) .

cluponka [151]

The formula of arithmetic sequence is
an = a₁ + d(n - 1)

Then we need to find the formula to determine n. I reverse the equation so the 'n' will be on the left side.
a₁ + d(n - 1) = an

Then I move all the terms on the left one by one to the right side except n
a₁ + d(n - 1) = an
d(n - 1) = an - a₁
n - 1 = (an - a₁)/d
n = 1 + (an - a₁)/d

This is the formula to solve n
n = 1 + (an - a₁)/d
