Answer:

-1/6

Step-by-step explanation:

<em>[remember: (-)(-) is (+) , (+)(-) is (-) , (+)(+) is (+)]</em>

-2/3 - (-1/2)

⇒ -2/3 + 1/2

LCM of 3 and 2 is 6,

⇒ -2 × 2/3 × 2 + 1 × 3/2 × 3

⇒ -4/6 + 3/6

⇒ -4 + 3 /6

⇒ -1/6

Answer:

x=25°, y=18°

Step-by-step explanation:

Solved! Here is the explanation. As we have supplementary angles, we have a total of 180° of angles. Angle BXD is a right angle, so 2x+40°=90°. 2x=50°, and then we have x=25°. Now, to figure out y, we have to look at angle BXA. In this case, 5y=90°. y=18°. So, x=25° and y=18°. Hope this explanation helps!
