(x+10)°+(2x+20)°=180°. I need this solved with work fully shown.( step-by-step ). thanks.

Answer:

x = 50

Step-by-step explanation:

Given

(x + 10) + (2x + 20) = 180 ( remove the parenthesis )

x + 10 + 2x + 20 = 180, that is

3x + 30 = 180 ( subtract 30 from both sides )

3x = 150 ( divide both sides by 3 )

x = 50

Answer:

$x < -20$

Step-by-step explanation:

Given the following question:

$x+8 < -12$

In order to solve one step inequalities, we solve how we would normally solve a one-step equation and then graph the answer on a number line.

$x+8 < -12$
$8-8=0$
$-12-8=-20$
$x < -20$

Now to graph the inequality on a number line, keep a few things in mind:
. x is less than -20 which means the line would go the opposite way of the negative 20.
. < is a greater than sign, not a greater than or equal sign (≤) so the number line will have a open point.
. The number line will have a point on -20.

Hope this helps.
