Answer:

answer is $\frac{23}{63}$

Step-by-step explanation:

the equation is

$\frac{5}{63}-(-\frac{6}{21} )$

=> $\frac{5}{63}+\frac{6}{21}$

=> $\frac{5}{63}+\frac{2}{7}$ ;(divide numerator and denominator of $\frac{6}{21}$ by 3)

=> $\frac{5+2*9}{63}$

=> $\frac{23}{63}$

A line passes through (10,4) and (13,-11). Write the equation of the line in standard form.

AlexFokin [52]

$\bf (\stackrel{x_1}{10}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{13}~,~\stackrel{y_2}{-11}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-11-4}{13-10}\implies \cfrac{-15}{3}\implies -5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-4=-5(x-10)$

now

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

therefore,

$\bf y-4=-5(x-10)\implies y-4=-5x+50\implies \blacktriangleright 5x+y=54 \blacktriangleleft$

A group of hikers buy 8 bags of trail mix. Each bag contains 3.5 cups of trail mix . The trail mix is shared evenly among 12 hik

ahrayia [7]

Each hiker will get 2.33333 cups of trail mix

If you need a mixed number the answer is 2 $\frac{1}{3}$

8×3.5=28

28÷12=2.33333
