Answer:
Step-by-step explanation:
The sum of the interior angles of a polygon with 
sides is 
. Since the shape in the figure has 5 sides, the sum of its interior angles is 
.
Therefore, we can set up the following equation:
Since 
and 
make up one side of a line, they are supplementary, as each side of a line is 
.
Thus, we have:
Answer:
Step-by-step explanation:
I'll start by finding the slope of this line using the slope formula:
Just by looking at the graph I know that the y-intercept is 20, so now I can write the equation in slope-intercept form (y=mx+b):
Answer:
Step-by-step explanation:
So basically what you want to do is start with the distributive property.
-0.5(x+0.3) = 1.6x+0.9(x+4.8) would then equal -0.5x-0.15 = 1.6x+0.9x+4.32.
Then, add the matching terms on the right side (the x values) 1.6x+0.9x =2.5x
Your equation should the look like -0.5x-0.15 = 2.5x+4.32.
Next, add -0.5x to 2.5x giving you 3x
The equation will look like -0.15 = 3x+4.32
After that subtract 4.32 from -0.15 leaving you with -4.47=3x
Divide 3x from both sides
Your answer should be x= -1.49.
I hope this was helpful and not super confusing! Also if anything is incorrect let me know! :)
You would multiply 1/7 and 14 to get your number so your answer is 2
