Find the measure of an angle whose supplement measures seventeen times its measure

Lilit [14]

supplement angles, sum = 180
lets x = angle
its supplement = 180 - x

x + 17x = 180
18x = 180
x = 10
180 -10 = 170

answer
angle = 10
its supplement = 170

I need help with these ASAP thanks

Answer:

a. $y=\frac{2x}{x-5}$

b. $y=\frac{2-4x}{x-3}$

Step-by-step explanation:

change switch x and y and then solve for y.

a. $x=\frac{5y}{y-2}$

$x(y-2)=5y$

$xy-2x=5y$

$xy-5y=2x$

$y(x-5)=2x$

$y=\frac{2x}{x-5}$

same for b.

b. $x=\frac{3y+2}{y+4}$

$x(y+4)=3y+2$

$xy+4x=3y+2$

$xy-3y=2-4x$

$y(x-3)=2-4x$

$y=\frac{2-4x}{x-3}$
