Desperate for the answer

if i give my sister 5 dollars, then we will have the same amount of money. if instead she gives me 8 dollars, then i'll have twice as much money as she has. how much money does she
have?

Let X = the amount you have and Y = the amount she has.

If you give her 5 you would have the same amount so you get an equation like:

X-5 = y +5

Simplify :

X – y = 5+5

X -y = 10  (Call this equation 1).

Now if she gives you $8 you will have twice as much as her, so set up the second equation:

2(y-8) = x +8

Simplify:

2y -16 = x +8

2y -x = 8 +16

2y -x = 24 (Call this equation 2).

Now add equation 1 and 2 together:

X – y = 10 + 2y -x = 24

Simplify to get y = 34

Now replace y with 34 in equation 1 to solve for x:

X -34 = 10, x = 44

You have $44 and your sister has $34

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

step-by-step explanation: the declaration of the rights of man and of the citizen (french: déclaration des droits de l'homme et du citoyen de 1789), set by france's national constituent assembly in 1789, is a human civil rights document from the french revolution.[1]

the declaration was drafted by the abbé sieyès and the marquis de lafayette, in consultation with thomas jefferson.[2] influenced by the doctrine of "natural right", the rights of man are held to be universal: valid at all times and in every place, pertaining to human nature itself. it became the basis for a nation of free individuals protected equally by the law. it is included in the beginning of the constitutions of both the fourth french republic (1946) and fifth republic (1958) and is still current. inspired by the enlightenment philosophers, the declaration was a core statement of the values of the french revolution and had a major impact on the development of freedom and democracy in europe and worldwide.[3]

the 1789 declaration, together with the 1215 magna carta, the 1689 english bill of rights (1689), the 1776 united states declaration of independence, and the 1789 united states bill of rights, inspired in large part the 1948 united nations universal declaration of human rights
