Do you want to get the variable by itself.
In order to do that subtract x on both sides.
-2x+9=-5
Then subtract 9 on both sides
-2x=-14
Divide by -2 on both sides
X=7
8-21
9- -16 i think lemme do the next ones
Answer:
A and E
Step-by-step explanation:
A = 2.3

D = 2.71
E = 2.3
F = 10.08
The question reminds you of all the tools you need:
It says ...
"Opposite angles are equal."
So the upper right angle is x+40 just like the bottom left,
and the bottom right angle is 3x+20 just like the upper left.
And it says ...
"The sum of all angles is 360°."
You know what each of the four angles is, so you can addum all up,
set the sum equal to 360, find out what number ' x ' is, and then
use that to find the size of every angle.
Answer: 11
Step-by-step explanation:
XY + YZ = XZ
XY + 3 = 14
