Answer:

$9x + \frac{7}{2} - (x - (x - \frac{2}{7} )) = 36 \\ 9x + \frac{7}{2} - x + x - \frac{2}{7} = 36 \\ 9x + \frac{7}{2} - \frac{2}{7} = 36 \\ 9x + \frac{49 - 4}{14} = 36 \\ 9x + \frac{45}{14} = 36 \\ 9x = 36 - \frac{45}{14} \\ 9x = \frac{504 - 45}{14} \\ 9x = \frac{459}{14} \\ x = \frac{459}{14 \times 9} = \frac{459}{126} \\ x = 3 . 64 \\ thank \: you$

Please help!!!!!!!!!!!!!

Answers:

Step-by-step explanation:

We must simplify each option to see if they are equivalent to $-\frac{3}{8}$ .

Lets try A.

$-\frac{6}{16}$ can be simplified to $-\frac{3}{8}$ by dividing both the numerator and denominator by 3.

$-\frac{6}{16}$ ÷ $\frac{3}{3} = -\frac{3}{8}$

A is correct!

Lets try B

$\frac{12}{32}$ simplifies to $\frac{3}{8}$ . However, because this answer is not negative, it is not equivalent.

Lets try C

There is a negative in the numerator, making this fraction negative. So yes, $\frac{-3}{8} = -\frac{3}{8}$ .

Bonus Info: If there was a negative in both the numerator and denominator, the two negatives would cancel eachother out, making the fraction positive

C is correct!

Lastly, Lets try D

There is a negative in the denominator, so this fraction is negative. $\frac{9}{-24}$ can be simplified by dividing by 3 to $-\frac{3}{8}$ .

$\frac{9}{-24}$ ÷3 = $-\frac{3}{8}$

D is correct!

Hope this helped you!~

What’s the angle of cda

Anastaziya [24]

Answer:

∠ CDA = 32.3°

Step-by-step explanation:

See the given figure attached to this answer.

Draw perpendiculars from B and C on AD which is BE and CF.

Now, Δ ABE is a right triangle and AE² = AB² - BE² = 7.5² - 6² = 20.25

⇒ AE = 4.5 cm

Now, DF = AD - EF - AE = 24 - 10 - 4.5 = 9.5 cm {Since BC = EF}

And CF = BE = 6 cm.

Now, Δ CFD is a right triangle and

$\tan \beta =\frac{CF}{FD} = \frac{6}{9.5} = 0.6315$ {Where β = ∠ CDA}

⇒ $\beta = \tan^{-1} (0.6315)=32.27$ Degree.

So, ∠ CDA = 32.3° {Correct to one decimal place} (Answer)
