Answer:
x=-1/2
Step-by-step explanation:
-3(x-4)= -9(x-1)
-3x+12= -9x+9
-3x+9x= 9-12
6x= -3
x=-3/6
x= -1/2
The distance between -6 and -3 on a number line is 3.
To find this out, simply divide 186 by 21. Which is 8.9 (i rounded it)
But you can just multiply (to check) 21 by 8 to geet 168. Any further, you would get a number higher than 186.
~Hope this helped :)
Supplementary angles are two angles that add up to 180 degrees. so....<3 + <4 = 180 <3 is 117 so sub in 117 for <3 117 + <4 = 180 <4 = 180 - 117 <4 = 63 degrees
