<span>2d= a-b/b-c solve for a
Okie, you mean: 2d=a-b:(b-c)
If that, we have a= 2d+b:(b-c)
Done!</span>
Answer: ∛v
Step-by-step explanation:
Since we know volume is measured height x width x length, we know the equation we'd use here would be:
___ x ___ x ___ = v in³
If this was area, we would have ___ x ___ = v in², and it would be easy to find each blank. You would just find the square root of "v", making your answer √v.
When you have 3 things multiplied by each other (that are exactly the same, which is the situation here since this is a cube), you will want to find ∛x (if x is our unknown variable). This means that we are finding ONE-THIRD of the number ... sort of. So if x was equal to 8, then ∛x = 2, because 2 x 2 x 2 = 8.
In our situation here, x = v, and since we don't know the actual number, we will keep it as a square root, so the answer to your question is ∛v.
I really hope I was able to explain easy enough, feel free to ask anything else!
Answer: 6cups of flour
Step-by-step explanation:
3cups of sugar to 2cups of flour
9cups of sugar to xcups of flour
Let sugar rep s
Flour rep f
So we have;
3s=2f
9s= xf
Cross multiply
3s×xf=2f×9s
Xf=2f×9s/3s
Xf=6f
Therefore, 9cups of sugar will be to 6cups of flour

<span> A ⊂ B means all of A is in B
but then it says </span><span>A ∩ B = θ meaning they have nothing in common, ie, none of A is in B or vice versa
A must be the empty set for both these conditions to hold. B could be anything you want. B could be empty, or it could not be. It's impossible to tell.
For certain, A must be empty. Which is why the answer is choice C</span>
