If the exchange rate when converting US dollars to Za rands is $1=R17

den301095 [7]

<h3>Given:</h3>

1 US Dollar= R17

How much is $100 in ZA rands.

<h3>Solution:</h3>

Let the unknown be "x"

$\frac{1}{17}×\frac{100}{x}$

We'll have to do cross multiplication.

So we'll have to multiply 100 and 17.

$100×17$

$\huge\boxed{= 1700 \: ZA \: rands}$

Therefore, $100 is 1700 ZA rands.

SUBTRACT 39 FROM 16 RAISED TO THE 7TH POWER, THEN MULTIPLY BY 3

MA_775_DIABLO [31]

I assume you mean 3(16^7-39)?

16^7 is 268435456

268435456-39 is 268435417

268435417 multiplied by 3 is 805306251

Hope this helped.

$\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{3})~\hspace{10em} slope = m\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-3=1[x-(-3)] \\\\\\ y-3=1(x+3)\implies y-3=x+3\implies y=x+6$

$\bf (\stackrel{x_1}{-4}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{12}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{12-2}{1-(-4)}\implies \cfrac{10}{1+4}\implies \cfrac{10}{5}\implies 2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-2=2[x-(-4)]\implies y-2=2(x+4) \\\\\\ y-2=2x+8\implies y=2x+10$
