Answer:
x = 22
Step-by-step explanation:
The sum of the angles round a point is 360°
Sum the given angles and equate to 360
x + 6x + 40 + 3x + 100 = 360
10x + 140 = 360 ( subtract 140 from both sides )
10x = 220 ( divide both sides by 10 )
x = 22
(2(3x4))+(2(4x8))+(2(3x8)) = 24+64+48 = 136
Answer: C
In order to solve this equation, let's write it out in number form:
-3 - x = -10
In order to isolate 'x' we need to ensure that there is only 'x' on one side. We can get rid of the -3 by adding 3 to both sides:
-3 + 3 - x = -10 +3
-x = -7
Because there are negatives on both sides, you can simply cancel them out:
x = 7
