Answer:

-12

Step-by-step explanation:

Convert the mixed number to an improper fraction.

-2\frac{2}{3} = -\frac{8}{3}

To divide, just multiply by the reciprocal.

So -2\frac{2}{3} ÷ \frac{2}{9} becomes -\frac{8}{3} ÷

Now you can multiply straight across.

-\frac{8}{3} × \frac{9}{2} = -\frac{72}{6}

And simplify.

-\frac{72}{6} = -12

For the first one we divide every element by sqrt3

we get

q+2/sqrt3 =sqrt5/sqrt3

q=(sqrt5-2)/sqrt3

q=sqrt3*sqrt5-2*sqrt3/3

q=sqrt15-2sqrt3/3

which is the third option

For the second one

sqrt(2y-5) +4=8

first we move the 4 to the right

sqrt(2y-5)=4

we remove the square root by bringing to the power of two

2y-5=16

2y=21

y=21/2

y=10 1/2

third option
