6b < 42 implies b < 42 / 6 = 7, so it is <span>b < 7
</span>4b + 12 > 8 implies 4b > 8 - 12 = -4, 4b > -4, and then b > -4 / 4 = - 1
the answe is <span>b < 7 or b > -1 </span>
option 4
Step-by-step explanation:
The first one is the correct answer
0 or if maybe another 0 for two ZER0s
X=40
Complementary=90 degrees
50+x=90
-50 -50
X=40
