What’s the Answer to this I got 24 somehow

Bess [88]

Answer:

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!

Divide 33 photos into 2 groups so the ratio is 4 to 7.

kvv77 [185]

So you want two groups that are in a ratio of 4 to 7
so 33=4x+7x
so 33=11x
so x=3

that means the groups are 4*3= 12 and 7*3=21

Explain the order in which you should compute the operations in the expression below.

Reptile [31]

1. You would divide the 33/3 first to get 11

2. Then you would add 1 to that answer to get 12

3. Then you would subtract 2^2 from that to get 8

Your answer would be 8.
