$\frac{5}{7} + \frac{3}{4} = \frac{5\times 4}{7\times 4}+\frac{3\times 7}{4\times 7}=\frac{20}{28}+\frac{21}{28}=\frac{20+21}{28} = \frac{41}{28} = \boxed{1\frac{13}{28}}$

ANSWER

C. 58°

EXPLANATION

The sum of the interior angles of a triangle is 180°.

We sum all the three angles to obtain,

$8x+(14x+2)+(10x+50)=180$ .

We group like terms to get,

$8x+14x+10x+2+50=180$ .

Simplify,

$32x+52=180$ .

Combine like terms to get,

$32x=180-52$ .

Simplify,

$32x=128$ .

Divide both sides by 32 to get,

$x=4$ .

We substitute the value of x into the expression for

$m\:$ .

This implies that,

$m\:$ .

The correct answer is C

A cube has a volume of 512 mm^3. If all sides of the cube are divided by 4, what will the resulting volume be?

pshichka [43]

$\bf \textit{volume of a cube}\\\\
V=s^3\qquad \boxed{s=\frac{s}{4}}\implies V=\left( \cfrac{s}{4} \right)^3\implies V=\cfrac{s^3}{4^3}\implies V=s^3\cdot \cfrac{1}{4^3}
\\\\\\
V=s^3\cdot \cfrac{1}{64}\impliedby \frac{1}{64}\textit{ of the original volume, if the original was 512}
\\\\\\
512\cdot \cfrac{1}{64}\implies \cfrac{512}{64}$

Answer:

3
1
-3
1
-3

Step-by-step explanation:

The change in y is the difference in y-coordinates between the lower right point and the upper left point. Similarly, the change in x is the difference in the x-coordinates of those points.

$\text{Slope}=\dfrac{\text{change in y}}{\text{change in x}}=\dfrac{\boxed{3}-6}{2-\boxed{1}}\\\\=\dfrac{\boxed{-3}}{\boxed{1}}\\\\\\=\boxed{-3}$
