12/15
Divide 12 by 15 and then you should get 0.8
0.8 is obviously equal to 8/10ths or 80%
Hope this helps :)

Answer:
28+66+86=180
180=180
Step-by-step explanation:
Since there is a triangle and the 3 measures from the angles we can find the value of x using the hint given that the sum of the interior angles must be 180°
Write the equation
\begin{gathered}x+(2x+10)+(3x+2)=180\\\end{gathered}
x+(2x+10)+(3x+2)=180
Simplify left side of the equation
\begin{gathered}6x+12=180\\\end{gathered}
6x+12=180
Solve equation for x
\begin{gathered}6x=180-12\\6x=168\\x=28\end{gathered}
6x=180−12
6x=168
x=28
Replace x into the 3 angles and find their respectives values
\begin{gathered}A=x\\A=28\\\\B=2x+10\\B=2*28+10\\B=56+10\\B=66\\\\C=3x+2\\C=84+2\\C=86\end{gathered}
A=x
A=28
B=2x+10
B=2∗28+10
B=56+10
B=66
C=3x+2
C=84+2
C=86
Check if the answers are correct
\begin{gathered}28+66+86=180\\180=180\end{gathered}
28+66+86=180
180=180

Answer:
The slope is 1/2 in the positive direction
Step-by-step explanation:
Let us start with the basic slope equation:
rise/ run= slope
Now if we look at our graph, we can derive that the line is increased.
Then we look at two parts of the line which lie on a proper point of the graph.
In this case, I looked at (-4,0) and (-2,1).
The rise in this case is 1 while the run is 2.
Putting this into the equation gives us 1/2.
Answer:
Slope-intercept form: y = 3 x + 4 Point-slope form: y − 7 = 3 ⋅ ( x − 1 )
