attashe74 [19]

Answer:

Step-by-step explanation:

Absolute Change = final change in 2017 sales - initial change in 2016 sales = $847,000,000 - $885,100,000 = 38,100,000

Relative Change = (Final - Initial change)/initial change x 100% = 38,100,000/885,100,00 x 100% = 381/8851 x 100% = 0.0430459835 x 100% = 4.30%

sergejj [24]

Answer:

11/9

Step-by-step explanation:

To find the slope

m = ( y2-y1)/(x2-x1)

= ( 9 - -2)/(1 - -8)

= ( 9+2)/ (1+8)

= 11/9

Someone help me with this ples with steps

SSSSS [86.1K]

Answer:

$x=\frac{21}{4}$

$y=\frac{21}{2}$

Step-by-step explanation:

equation (1): $\frac{1}{2} (2x+y)=\frac{21}{2}$

equation (2): y=2x

solve the system by substitution

step1: sub (2x) for y in equation 1:

$\frac{1}{2} (2x+y)=\frac{21}{2}$

$\frac{1}{2} (2x+2x)=\frac{21}{2}$

step2: simplify the expression:

$\frac{1}{2} (4x)=\frac{21}{2}$

$2x=\frac{21}{2}$

(divide by 2 for both sides)

$x=\frac{21}{4}$

To find the value for y sub 21/4 for x in equation 2:

y=2x

y=2×(21/4)

$y=\frac{21}{2}$

Work out the number of sides of a regular polygon with the interior angle of 172 degrees.

Harman [31]

$interior\ angle=\frac{(n-2)*180}{n}\\n-number\ of\ sides\\\\
172=\frac{(n-2)*180}{n}\ \ \ |*n\\
172n=180n-360\ \ \ |Subtract\ 180n\\
-8n=-360\ \ \ |Divide\ by\ -8\\
n=45\\\\
Number\ of\ side\ is\ equal\ to\ 45.$
