Solve for x using the distributive property. 9(5 - x) = 81 x = [?]

Ilya [14]

Answer:

$\boxed {x = -4}$

Step-by-step explanation:

Solve for the value of $x$ :

$9(5 - x) = 81$

-Use Distributive Property:

$9(5 - x) = 81$

$45 - 9x = 81$

-Subtract $45$ to both sides:

$45 - 45 - 9x = 81 - 45$

$-9x = 36$

-Divide both sides by:

$\frac{-9x}{-9} = \frac{36}{-9}$

$\boxed {x = -4}$

So, the value of $x$ is $-4$ .

The point (1,-1) is on the terminal side of angle theta in standard position what are the values of sine cuisine and tangent of

pickupchik [31]

$\bf \textit{terminal point }\implies 
\begin{array}{lclcll}
(&1&,&-1)\\
&\uparrow &&\uparrow \\
&x&&y
\end{array}
\\\\\\
sin(\theta)=\cfrac{y}{r}
\qquad 
% cosine
cos(\theta)=\cfrac{x}{r}
\qquad 
% tangent
tan(\theta)=\cfrac{y}{x}\\\\
-----------------------------\\\\
\textit{so, what's the radius "r"?}\implies r^2=x^2+y^2\implies r=\sqrt{x^2+y^2}$

Michael cycled a distance of miles in hours. What is his cycling unit rate in miles per hour?Michael cycled a distance of miles

notka56 [123]

Answer:

The number of miles/the number of hours

Step-by-step explanation:

If the number of hours is not equal to 1, multiply the numerator and denominator by the inverse of the number of hours.

For example, 10 (miles)/2 (hours)

The inverse of 2 is 1/2, so --> the new equation is 10/2 * 1/2 / 1/2 or

10* 1/2 and 2 * 1/2

When multiplied out, this leads to 5/1 or 5 miles per hour
