Answer:

Second option "B. 4" is the correct choice.

Step-by-step explanation:

$(-8)^{\frac{2}{3}}\\\\\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^{\frac{m}{n}}=\left(-1\right)^{\frac{m}{n}}\left(a\right)^{\frac{m}{n}}\\\\=\left(-1\right)^{\frac{2}{3}}\cdot \:8^{\frac{2}{3}}\\\\=1\cdot \:8^{\frac{2}{3}}\\\\=8^{\frac{2}{3}}\\\\=\left(2^3\right)^{\frac{2}{3}}=2^{3\cdot \frac{2}{3}}=2^2\\\\=4$

What is the answer to 18 - 3w = 4w

adelina 88 [10]

Answer:

Step-by-step explanation:

$18 - 3w = 4w$

Let's get all of the terms with the $w$ on the right-hand side of the equation, and everything else on the left-hand side of the equation.

To do this, we should add $3w$ to both sides of the equation to remove the $-3w$ from the left-hand side of the equation:

$18 - 3w + 3w = 4w + 3w$

$18 = 7w$

Finally, to get the $w$ by itself, we can divide both sides by $7$ :

$\frac{18}{7} = \frac{7w}{7}$

$w = \frac{18}{7}$

Answer:

The answer is B. He spent 3 minutes eating lunch for every 10 minutes.

Step-by-step explanation:

He spent stuck inside during the brainstorm for:

20+18+12+10= 60 minutes in total.

And now we want to know what he did for every 10 minutes he spent in the rainstorm. To do that we need to divide what he did for every 10 minutes by the total of minutes that he was stuck:

$\frac{10}{60} =\frac{1}{6}$
