Hi!

The answer is Magnusson!

Remember, the niece stated that the Amazing Alexis was NOT Magnusson's grandfather.

This is true.

However, it is also true that Magnusson, as he stated, was Alexis' grandson!

The key to this puzzle, is that you had to know that...

The Amazing Alexis was female!

Indeed, I do, Queen of the Forum.

If thou wilt knoweth, knoweth it as Andrew...

but I shalt be known as Anonymous4338 in thy kingdom.

P.S. I doth try hard to...

To my dearest forum members,

Thy message board hath been transf'rm'd to one of a strange dialect, hon'rable Guest! May I inquire, hast thou rememb'r'd me hither? To all of our humble kingdom, thou art great! I oweth all to thou! Thou canst withstandeth the hardships of the trolls.

I can show you how to solve for both x and y...

y = 2x - 3

We must always, if doing it to one, do something to another.

Let's solve for x first.

Add 3 to each side...

y + 3 = 2x

And divide by 2 on each to make 2x just x...

y/2 + 1.5 = x

x = 1/2y + 1 1/2

We can also solve for y...

y = 2x - 3

After thinking about it for a second, I just realized that the solution is

y = 2x -3

Huh. I guess you're looking for x. 

In that case, then the answer is, as said by Guest...

x = 1/2y + 1 1/2

-3-(-11/9)

Let's follow PEMDAS and solve what's in the parentheses first.

-11/9= -1 2/9

Now, we have...

-3 - (-1 2/9)

Subtracting a negative from something is the same thing as adding it, so let's make our lives easier and change the equation to...

-3 + 1 2/9

That's easier! I think you can solve the rest...

-3 + 1 2/9

Your wording is a bit confusing...

If you mean 705/4695, then the answer is 0.15, rounded to the nearest hundredth.

If you mean 4695/705, then the answer is 6.66, rounded to the nearest hundredth.

I'd like to show some work.

5p+2=4p-1

Let's move all the ps one side and the constants to the other.

First, subtract 4p from each side to keep p on the left.

5p-4p=p

4p-4p=0

Now we have p+2=-1

Next, subtract 2 from each side to get rid of the constants on the left.

2-2=0

-1-2=-3

p=-3

In conclusion, when 5p+2=4p-1...

p = -3

Next equation!

7a+10=2a

Let's do the same thing.

Subtract 7a from each side...

7a-7a=0

2a-7a=-5a

So, 10=-5a

Now, let's solve to make -5a just a.

10/-5=-2

-5a/-5=a

a=-2

In conclusion, If 7a+10=2a, then...

a = -2

I'll be on for maybe a half hour more, but I agree, the forum is getting a bit quieter.

Whoops, I think I answered this incorrectly.

I think you are looking for the price that the store got the spools for ($0.40) over the difference ($0.22).

Our equation is

x/100 = 0.40/0.22

Refer to my first post if you are confused.

Way 1:

0.40/0.22= 1 81/99

What does x have to be for x/100 to equal 1 81/99?

I suggest rounding to the nearest hundredth. 

Way 2:

0.4 * 100 = 40

x * 0.22 = 0.22x

0.22x = 40

What does x have to be for 0.22 * x to equal 40?

Hope at least one of the answers I supplied helped.

P.S. I just realized that you're probably the one posting all of the questions about mark-ups and sales taxes.

Would you mind showing us where you need help with? Maybe show some work?

I'm just a bit concerned that you might be posting all of your homework here in order to finish it up quickly for tomorrow.
