One teacher wants to give each student two and 1/6 slices of pizza if the teachers had 13 slices of pizza how many students will

hram777 [196]

Answer:

6 students.

Step-by-step explanation:

First let's combine 2 and 1/6.

6/6 + 6/6 + 1/6 = 13/6.

Now we will turn 13 to 13/1 and divide by 13/6

$\frac{13}{1} \div \frac{13}{6} = \frac{13}{1} \times \frac{6}{13}$

$\frac{13 \: \times \: 6 \: = \: 78}{ 1 \times \: 13 \: = \: 13}$

$78 \div 13 = 6$

So, the teacher will hand the pizza out to 6 students.

Which expression is equivalent?

iVinArrow [24]

Answer:

$\large\boxed{\dfrac{g^{15}}{8h^6}}$

Step-by-step explanation:

$\dfrac{\left(2g^5\right)^3}{\left(4h^2\right)^3}=\dfrac{\left(2g^5\right)^3}{\left(2^2h^2\right)^3}\qquad\text{use}\ (a^n)^m=a^{nm}\ \text{and}\ (ab)^n=a^nb^n\\\\=\dfrac{2^3g^{(5)(3)}}{2^{(2)(3)}h^{(2)(3)}}=\dfrac{2^3g^{15}}{2^6h^6}=\dfrac{2^3g^{15}}{2^{3+3}h^6}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=\dfrac{2^3g^{15}}{2^3\cdot2^3h^6}=\dfrac{g^{15}}{8h^6}$
