3.3(n-8)-n=1.2<br><br> Simplify! ::)

nydimaria [60]

Answer:

n=12

Step-by-step explanation:

3.3(n-8)-n=1.2

Distribute

3.3n -26.4 -n = 1.2

Combine like terms

2.3n -26.4 = 1.2

Add 26.4 to each side

2.3n -26.4+26.4 = 1.2 +26.4

2.3n = 27.6

Divide each side by 2.3

2.3n/2.3 = 27.6/2.3

n=12

Rewrite the expression using only positive integer exponents.

Andrews [41]

Answer:

So we got:

$\left(m^{\frac{2}{3}}n^{\frac{-1}{3}}\right)^6$

$m^4\left(n^{\frac{-1}{3}}\right)^6\\$

More attention for $(n^{\frac{-1}{3}}\right))^6\\$

$n^{-2}$

$\frac{1}{n^2}$

Join:

$m^4\frac{1}{n^2}$

$\frac{1\cdot \:m^4}{n^2}\\\frac{m^4}{n^2}$

Therefore, the answer is $\frac{m^4}{n^2}$ , letter A

High of the following transformations does not result in a congruent figure

LuckyWell [14K]

Any transformation involving change of scale will not result in a congruent figure. Rotations and reflections and translations maintain congruence.
