<span>m</span> = -4
<span>m</span>-4=2m
-4+m=2m (reorder)
-4 + 1m + -2m = 2m + -2m (added -2m to both sides)
-4+ -1m =0 (added like terms)
-4 +4+ -1m = 0+4 (added 4 to each side)
-1m = 4
m=-4 (divided by -1)
50°
angle CXF and DXF are complementary which means they add to 90°
to 40° + x = 90
x = 50
Answer:
50%
Step-by-step explanation:
The numbers that are 2 and even are 2 and 4.
2 numbers out of 4.
2/4 = 1/2
= 0.5
P(2 or even) = 50%
Answer:
B, it's the only plausible one. A is wrong because the value would be above 180°
