Write 75% as a decimal and fraction in simplest form.<br> SHOW ALL WORK.
Andrews [41]
75% means 75 per cent, or per hundred.
"Per cent" means "per hundred" or "0.01".
This means that 75% is 0.75 in decimal form.
75% as a fraction means 75 per hundred.
Keep in mind that "per" means to divide.
So, let's translate this into parenthesis.
75 (75) per (/) hundred (100).
Rewrite with only the parenthesis.
75 / 100.
This is 75% in fraction form, but isn't simplified. We can divide both numbers by 25.
75 / 25 = 3
100 / 25 = 4
Your simplified fraction is 3/4.

I hope this helps!

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
