<u>To find the simplified expression of (-2 - 8x) + (-4x - 10)</u>

Let expression is given by

(-2 - 8x) + (-4x - 10) = -2 - 8x -4x -10

= -2 -10 -4x -8x

= -12 -12x

-12(x + 1) (since -12 is common in both terms)

Therefore simplified form is -12(x + 1)

RoseWind [281]

The evaluation of 84 2/3% to a fraction in its lowest term is $\mathbf{ \dfrac{127}{150} }$

<h3>What is a fraction?</h3>

Fractions are sections or parts of a whole. They are divided into two parts, the numerator, and the denominator.

From the given information, we are to convert a mixed fraction into its lowest terms. By doing that, we are to convert it to an improper fraction.

$\mathbf{= 84 \dfrac{2}{3}\%}$

$\mathbf{= \dfrac{(84 \times 3)+2}{3} \%}$

$\mathbf{= \dfrac{254}{3} \%}$

$\mathbf{= \dfrac{254}{3} \times \dfrac{1}{100}}$

$\mathbf{= \dfrac{254}{300} }$

Divide both the numerator and denominator by (2)

$\mathbf{= \dfrac{127}{150} }$

Please help me with this and find x!! Thank you, only if you know!

scoray [572]

Answer:

x = 9.8

Step-by-step explanation:

to find x, use pythagorean theorem

$a^{2} = c^{2} - b^{2}$

$a^{2} = 14^{2} - 10^{2}$

$a^{2} = 196 - 100$

$a^{2} = 96$

$\sqrt{a^2} = \sqrt{96}$

$a = 9.7979$ ⇒ 9.8

asambeis [7]

Answer:

The grade point average of the student is 49.92.

Step-by-step explanation:

A student earned grades : C, A, B, and A

Corresponding numbers of credit hours : 44, 66, 11, and 66

Assigns quality points to letter grades :

A = 4 , B = 3 , C = 2 , D = 1 , F = 0

The grade point average (GPA):

$\frac{\sum (\text{grade point}\times \text{credit hours})}{\sum (\text{grade point})}$

$=\frac{2\times 44+4\times 66+3\times 11+4\times 66}{2+4+3+4}$

$=\frac{649}{13}=49.9230\approx 49.92$

The grade point average of the student is 49.92.
