If five more than twice a number is seventeen, then just twice the number is five less than seventeen. So, twice the number is seventeen minus five, which is twelve. Twice the number is twelve. Now, to find the number by itself, we need to divide twelve by two. So, the number is six.
We can check our answer like this: is five more than six times two seventeen?? Well, six times two is twelve. Five more than twelve is seventeen. So, we are right.

• find the missing information for the triangle

Savatey [412]

Answer:

You either need two sides and the angle between them or two angles and the side between them. Otherwise, you can construct a family of triangles that include the given pieces.

Step-by-step explanation:

"How do you find the missing sides of a triangle?"

I'm not a mathematician, but it seems to me that no one can find the missing sides (note the plural: "sides") of a triangle by having just one -- or none. You need at least two sides to get an answer...

Use the Line Tool to graph the equation. 2x−7y=14

kirza4 [7]

Convert to Y=MX+B to make it easier, minus 2x from both sides to get -7y=-2x+14, then divide it all by -7 to get y=2/7x-2. 2 equals your starting point, from there go down 2 and over 7 for you slope and repeat until the graph is done.

The surface area of the cone is 43.75pie cm^2. What is the slant height of the cone and the diameter is 5

Masteriza [31]

If the diameter of the cone is 5, then the radius of it will be half that, or 2.5, thus

$\bf \textit{total surface area of a cone}\\\\
SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~
\begin{cases}
r=radius\\
h=height\\
------\\
SA=43.75\pi \\
r=2.5
\end{cases}
\\\\\\
43.75\pi =\pi (2.5)\sqrt{r^2+h^2}+\pi (2.5)^2
\\\\\\
43.75\pi -\pi (2.5)^2=2.5\pi \sqrt{r^2+h^2}
\\\\\\
43.75\pi -6.25\pi =2.5\pi \sqrt{r^2+h^2}\implies 37.5\pi =2.5\pi \sqrt{r^2+h^2}
\\\\\\
\cfrac{37.5\pi }{2.5\pi }=\sqrt{r^2+h^2}\implies 15=\sqrt{r^2+h^2}$
