What’s the Answer to this I got 24 somehow

Bess [88]

Answer:

0

Step-by-step explanation:

So we have the expression:

$\frac{2x+y}{xy-2x}$

And we want to evaluate it for x=-4 and y=8.

So, substitute:

$\frac{2(-4)+(8)}{(-4)(8)-2(-4)}$

Multiply:

$=\frac{-8+8}{-32+8}$

Add:

$=\frac{0}{-24}$

Evaluate:

$=0$

So, our answer is 0.

And we're done!

A piece of green jade has a mass of 23.401 g.if the sample of jade displaces 50.0 ml of water to 56.5 ml in a 100 ml graduated c

OleMash [197]

we know that

The density is equal to the formula

$Density=\frac{mass}{volume}$

in this problem we have

$mass=23.401\ gr$

<u>Find the volume of a piece of green jade</u>

$Volume=56.5\ ml-50.0\ ml=6.5\ ml$

Substitute the values in the formula of density

$Density=\frac{23.401}{6.5}$

$Density=3.60\frac{gr}{ml}$

therefore

<u>the answer is</u>

$Density=3.60\frac{gr}{ml}$
