469.1 mg = .4691 g. Hope I helped. =)
8x + 6=4x + 38
4x = 32
x = 8
<B = 4x + 38 = 4(8) + 38 = 70
Let d(x) = 2x - 4
Or
y = 2x - 4
We have replace x = y
x = 2y - 4
Now Isolate "y"
x + 4 = 2y
Pass "2" dividing
(x + 4) / 2 = y
y = x/2 + 2
Or
d(x)^-1 = x/2 + 2
9. <span>1.25 = (1 x 1) + (2/10) + (5/100)
11. is ---C----</span>
I don't know if I understand the question but I think it is 15
