11x - 3 = x - 13
-x -x
10x - 3 = -13
+13 +13
10x = 10

10 10
x = 1
Answer:
The value of x are all real number on x-axis the number that falls under x
example of the value of x are in this equation
y=2+5x
2x+6y=60
to find x
let make the first one equation 1 and the second equation 2
now, put equation 1 in equation 2
2x+6(2+5x)=92
open the by multiplying every thing in the bracket by 6
2x+12+30x=92
combine the like terms
2x+30x=69212
32x=80
now divide via by 32
32x/32=80/32
x=5/2
Answer:
111°
Step-by-step explanation:
- All these are parallel lines, so the 36° angle is equal to the 36° angle inside the big triangle because they are vertically opposite.
- Ignore the line cutting between 45° and the 30° and consider it as one triangle
- Add them to get 75°
- Now you have two known angles 75° and 36°
- To get angle <em>x</em><em> </em>add 75° and 36° to get 111°
- Because x° is an exterior angle and exterior angles equal to the sum of interior angles opposite it inside the triangle.
I don't understand what the question is.. there are no spaces..
