My bad, read it wrong! Thanks, EP!

We have 0.22mm for 8cells, so for one cell it is: $\frac{0.22}{8}=0.0275mm$

Wir haben $-7x-14-4 + 3x = -4x + 18$, und das entspricht $-4x-14-4 = -4x + 18, -4x-18 = -4x + 18, -18$ und $18$.

Hint: Use the lines, that lie on each side of the triangle! They mean that the angles are congruent!

We have two ratios. 

Girls: $12:40=3:10$

And, for the boys: $16:40=4:10=2:5$.

Thus, the answer is $\boxed{NO}$.

Ugh, I have to read from the table. Well, whatever, I'll try. For, City 2, we have $7+17+20+19+7+2=72.$ And, the mean is just $\frac{72}{6}=\boxed{12}.$

one person: $\frac{2}{8}$ of a pizza, or $\frac{1}{4}$ of a pizza.

Since we have $3$ pizzas, there will be $\frac{3}{\frac{1}{4}}=3*4=\boxed{12}$ people.

Yes, it's in the form $ax^2+bx+c$, and you plug the values into this formula: $x = {-b \pm \sqrt{b^2-4ac} \over 2a}$. Neat that web2.0calc gives you the quadratic formula, when you press the latex button! Remember that, $\pm$ is plus or minus.

You can break the original value into $\sqrt[3]{16}\sqrt[3]{x^5y^{13}}.$ We know that $\sqrt[3]{16}=2\sqrt[3]{2}$, because of the power,  $2^4.$ Thus, the answer is $\boxed{2\sqrt[3]{2}\sqrt[3]{x^5y^{13}}}$.

Thanks, CPhill!
