What sums are equal to 6/12?

nadya68 [22]

Hey there!

"What sums are equal to $\bold{\frac{6}{12}}$ ?"

$\bold{\frac{6}{12}=\frac{1}{2}=0.5 }$

It can't be $\bold{A. \frac{6}{12} + \frac{6}{12}+ \frac{6}{12}+\frac{6}{12}+\frac{6}{12}+\frac{6}{12}}$ because the answer would be $\bold{3}$
It can be $\bold{B.\frac{2}{12} + \frac{1}{12} + \frac{1}{12} +\frac{2}{12}}$
It can also be $\bold{C. \frac{5}{12} + \frac{1}{12}}$
It can also again be $\bold{\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{3}{12}}$
$\boxed{\boxed{\bold{Answers: B,C,D}}}}$

Good luck on your assignment and enjoy your day!

Alex17521 [72]

$\begin{gathered} 8x+3y=7\ldots eqn(1) \\ 4x+y=1\ldots.eqn(2) \end{gathered}$

The property that justifies multiplying through eqn(2) by -2 is;

the rationalization to align the coefficients of x in both equations with a view to eliminating the terms in x.

Use change-of-base formula to find three significant digits log^6 120

Change of base formula:
loga b=logc b / logc a

log₆ 120=ln 120 / ln 6=2.67

Answer: log₆ 120=2.67
