We need to know how many marbles we're drawing out of the bag....one??....two??......three??
OK.....so we have
2x + 8 = 8(x - 5) And expanding gives
2x + 8 = 8x - 40 Subtract 8x from both sides and 8 from both sides
-6x =-48 Divide both sides by -6
x = 8
$${\mathtt{20\,000}}{\mathtt{\,\times\,}}{\left({\mathtt{1.09}}\right)}^{{\mathtt{10}}} = {\mathtt{47\,347.273\: \!491\: \!842\: \!344\: \!680\: \!2}}$$
≈ $47347.27
$${{\mathtt{5}}}^{{\mathtt{7}}} = {\mathtt{78\,125}}$$
OK......but consider this......
I'll give you (2 + 2) dollars every day for a year
And you can give me 5 dollars every day for a year
And since we claim that 2 + 2 = 5
We should both be happy
Right idea.....but wrong execution.....
x < 512
Whatever "x" is, it's less than 512......
Simpify what ???
You could do it by hand.....but it gets pretty tedious, sometimes....(almost impossible, at others)
The on-site calculator will handle this operation just fine....try it !!!
Add 16 to both sides
x^2 = 3 Take the square root of both sides....remember, we need to take both roots - positive and negative
x = ±√(3)
And that's it.......
It looks like you want to find a missing dimension, but I can't tell from your question which one you're missing.
I'll let "x" represent the missing dimension and you can plug it in where you need to.....
3 * 4 * x = 144
12 * x = 144 Divide by 12 on each side
x = 12
