Answer:
131 degrees
Step-by-step explanation:
When you take all parts of the circle and add them up, you are given 31y-12.
When you set 31y-12 to 360 (31y-12=360), you can solve for y and plug it in to all variables of the circle.
31y-12=360
Add 12 to both sides to cancel it out from the left.
31y=372
Divide 31 on both sides to cancel out and leave y on the left.
y=372/31
y=12
Now, plug 12 in to each variable. 54+77=131 degrees
Answer:
Therefore, the equation of the line that passes through the point (-5,5) and has a slope of -8/5 will be:
Step-by-step explanation:
Given the point (-5, 5)
slope = m = -8/5
Using the slope intercept form:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Plugging point (-5, 5) and slope = m = -8/5 in the slope intercept form to find the y-intercept 'b'.
![5=\frac{-8}{5}\left(-5\right)+b](https://tex.z-dn.net/?f=5%3D%5Cfrac%7B-8%7D%7B5%7D%5Cleft%28-5%5Cright%29%2Bb)
![\mathrm{Switch\:sides}](https://tex.z-dn.net/?f=%5Cmathrm%7BSwitch%5C%3Asides%7D)
![\frac{-8}{5}\left(-5\right)+b=5](https://tex.z-dn.net/?f=%5Cfrac%7B-8%7D%7B5%7D%5Cleft%28-5%5Cright%29%2Bb%3D5)
![8+b=5](https://tex.z-dn.net/?f=8%2Bb%3D5)
![8+b-8=5-8](https://tex.z-dn.net/?f=8%2Bb-8%3D5-8)
![b=-3](https://tex.z-dn.net/?f=b%3D-3)
so the equation of the line will be:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
plugging m = -8/5 and b = -3 in slope intercept form
Therefore, the equation of the line that passes through the point (-5,5) and has a slope of -8/5 will be:
Answer:
D
Step-by-step explanation:
1. Add the costs together 10.98+13.95+22.56=47.49
2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.
47.49/3=15.83
The option closest to our number is D so we round up.
$15.83->$20
Have a good day.
