Answer:
12
Step-by-step explanation:
.......................
1.
<span>1.5x-1 > 6.5
1.5x>1+6.5
</span>1.5x>7.5, divide by 1.5
x>5, is represented by the region to the right of the vertical line x=5
2.
<span>7x+3 < -25
7x<-25-3
7x<-28, divide by 4:
x<-4
</span>x<-4, is represented by the region to the left of the vertical line x=-4
Answer: check the picture

Answer:
CB= 4
Step-by-step explanation:
the triangles are in AA similarity.
AB/AD = BC/DE
4/12 = x/12
CROSS MULTIPLY;
x = 48/12
x = 4
